➜  fuc git:(master) ✗

I cloned a project and I looked at the value of yarn.lock, package key 'resolved', which starts with 'http://npm.byted.org'.

I think this is the author custom yarn registry, but I can not visit 'http://npm.byted.org', but yarn config did not fix it.

[torifat]

What do you mean by "but yarn config did not fix it"? What did you try?

[id77]

expected:
If 'yarn.lock resolved' is unreachable, can I ignore 'resolved' in yarn.lock and install it using 'yarn config registry'.

doubt:
Or recommend me delete the lock file?

Sorry, forgive me, my English is not good.

[torifat]

Sorry, forgive me, my English is not good.

It's not a problem as long as I can understand. And, I'm also not very good either 😄

It's not a bug. This is an expected behavior. You can either delete yarn.lock file and yarn install again. Or, if you need the exact packages then you can replace http://npm.byted.org with https://registry.yarnpkg.com in yarn.lock file.

[marcelhageman]

Adding this comment for other Googlers: What worked for me was increasing the Yarn network timeout:

yarn add YourPackageHere --network-timeout 100000

Apparently the package I was installing was too large (or my network too slow) so it assumed it was a network problem. It might've been, but this solved it. Just took a while.

[AnthonyLamot]

I'm experiencing this issue now as well. None of the aforementioned solutions seem to be working. Internet still works fine though, and no one else in the co-working space where I'm at seem to be experiencing any network issues?

[AnthonyLamot]

Figured out was wrong. One of my dependencies (react-native itself) had the
wrong value and it got stuck there. Took me a while to realize because it
did not show in the error report but only while the yarn command was
running would it pop up for a moment.

[JochenFromm]

Same problem here, increasing the network timeout solved it

yarn install --network-timeout 1000000

Maybe the default timeout is too small?

[HarshulSharma000]

I am facing the same issue on Windows and setting timeout does not resolve it. On the other hand npm works fine.

FAILURE: Build failed with an exception.

Any help here ?

[jensbodal]

Don't have a solution or why there was network issues in the first place, but the default for NETWORK_TIMEOUT is 30 seconds. Note that network-timeout is in ms, I probably wouldn't set this to higher than 5 minutes otherwise your build will just sit there for ~16 minutes (1000000ms) is there truly is network connectivity issues.

https://github.com/yarnpkg/yarn/search?utf8=%E2%9C%93&q=NETWORK_TIMEOUT&type=

[marcelorl]

@HarshulSharma000 same issue

[HarshulSharma000]

@marcelori I tried to revert to nodejs 8.9.4(lts) and then tried with --network-timeout=99999 and it works.
Note:- I am using yarn 1.4.0

[suhailgupta03]

Looks like yarn was trying to connect via a proxy. The following worked for me:

npm config rm proxy
npm config rm https-proxy

[jesper-bylund]

I'm still having this issue. Increasing network timeout did not help, nor did @suhailgupta03 's proxy removal. Right now, yarn won't install, add, or do anything. I've tried it through three different networks.

[benseitz]

same here......

[abishekrsrikaanth]

same here

[MichelDiz]

"is there truly is network connectivity issues." I don't think so. I have 100Mb of internet. No services are with trouble. Downloads are perfect, VOIP is perfect, NPM shines. Only Yarn I have this... Something dark is happening.

UPDATE: I did some voodoo trick and works fine now https://github.com/yarnpkg/yarn/issues/5259#issuecomment-379769451

[adjavaherian]

Might be by design. There's a registry in ~/.yarnrc that's autogenerated. Perhaps its behind a VPN or something?
```
cat ~/.yarnrc

THIS IS AN AUTOGENERATED FILE. DO NOT EDIT THIS FILE DIRECTLY.

yarn lockfile v1

registry "https://artifactory.some.net/api/npm"
lastUpdateCheck 1233305747

[MichelDiz]

mine (Looks like the registry address is empty - was not it supposed to contain something?):

=> cat ~/.yarnrc
# THIS IS AN AUTOGENERATED FILE. DO NOT EDIT THIS FILE DIRECTLY.
# yarn lockfile v1


lastUpdateCheck 1523327705543

But, until now the "voodoo trick" is working great for me.

[jesper-bylund]

@adjavaherian This works! Mine was stuck to a VPN URL at my company. NO idea why it was set to that though. Because I don't use the VPN for yarn at all.

[learntoswim]

The "voodoo" trick posted above by @MichelDiz worked for me as well.

[Deja-vuuu]

So,How to solve this problem?
I ran into the same problem on Windows.

[Ryuurock]

+1

[cp1001]

this kind of error occurs when your net cannot access some package resource which yarn.lock file specified.
check your yarn.lock file or delete yarn.lock,then change npm registry to other public regitstry,then yarn install.

point are:
donot use private registry.
check your network's connection to registry.

[FDiskas]

[ppozeti]

thought it was a problem with my private proxy npm, but I'm glad I'm not alone! Same problem is happening. If I copy the registry url and paste on chrome, it downloads the file.

[spitchaiah]

This worked for me:

$ yarn config delete proxy
$ yarn install --network-timeout 1000000

[Vadorequest]

Having those troubles now but https://registry.yarnpkg.com is not responding either, may be a general outage?

---

Edit: After checking https://status.yarnpkg.com/ I figured my wifi connection somehow couldn't connect to that particular URL. other website work fine... Changed to mobile network and then it works.

[FDiskas]

Why this clone of all modules is used? Why not directly from npm?
Collecting more info when and why downloading?

[somewhatabstract]

For me, this was because I had added two factor auth to my npmjs.org account.

I ran:

npm logout
npm login

Then filled out the details, including the MFA OTP request. Then everything worked again.

[zbsedefian]

Vadorequest, same issue. I get back some JSON when I use my cellular network. 404 when I use my wifi network.

[Vadorequest]

Maybe it's related to internet providers then, maybe for some reason some URLs are blocked. I don't see any other reason why it'd fail on wifi and work on through 4G. But that's really odd if so.

[jreybaylen]

@Vadorequest did you solve your problem? I encountered it too.

[Vadorequest]

Not really, can't explain it. I just switched to a mobile network and it worked. Now I'm back on my wifi and it works too. Maybe restart your network or switching to another may fix it.

[simon-robertson]

I started to encounter the same issue today. Deleting the proxy resolved the issue for me.

yarn config delete proxy

[zbsedefian]

It works this afternoon without me having to delete proxies or adjust anything.

[yzhe8769]

I have encountered the same issue on my Mac. But this seems to be related to the DNS setting in the machine. What I have done is to manually set my DNS server to 8.8.8.8 (Google DNS) and 208.67.222.222 (Open DNS) and now it is resolved. I can run 'yarn install' again.

[FDiskas]

I had no problems on mac and linux only on windows there was such error. It could be related to platform also.

[prasadram]

@yzhe8769 do you know how to change DNS settings in ubuntu ? i want to try that options as well, because i have tried almost all options

[prasadram]

After investigating resolved the issue. Please check below are my analysis
when i hit below command i got unknow host

curl registry.yarnpkg.com
curl: (6) Couldn't resolve host 'registry.yarnpkg.com'

i am using Desktop with LAN and OS is ubuntu 16.04 but the same command is working fine in mac
then realized it's not with yarn so i have added google dsn in resolv.conf in etc folder then started working fine.
hope it will help someone

All good. So if anyone also encounters this issue, that is probably because the DNS setting is preventing the resolution of the yarn registry

Specifying another folder for cache resolved the issue in my environment :

[kirillgroshkov]

is network-timeout documented anywhere? Google doesn't give me anything..

[whereisaaron]

@torifat could you consider reopening this issue. The problem here is all the 'info There appears to be trouble with your network connection. Retrying...' messages. These occur whether or not you have a lock file. If I delete my yarn.lock file I still get these messages. If I delete the yarn cache and lock file. I get even more.

This error message issue appears to have resurfaced by PR #6413 which recently added this message as part of a retry mechanism because or remote npm registry problems, and is usually nothing to do you 'your' end. It seems to be a congenital problem with the registry causes retries, and that being surfaced by these messages.
https://github.com/yarnpkg/yarn/pull/6413/files#diff-5d246f90b159bd84bbc99f67527b1a0eR401

It seems like the problem is actually that this message is misleading.

@arcanis tells me that yarn 1.11+ will have a more accurate message when the retry is caused by the npm registry, as #6413 also includes a new, more accurate message that is not in yarn 1.10.x.

[torifat]

@whereisaaron Can you please create a new issue? I think it's better to create a new one instead of resurrecting an old issue with lots of comments.

[whereisaaron]

Sure @torifat; I didn't want to keep making duplicate issues. Right now though, this one might be resolved when 1.11 releases, so let's leave it closed, and if 1.11 still has any problem I'll open a new issue for that version specifically.

[TedSean]

Even i m facing the issue.

[keicoon]

Even i m facing the issue(2) in 1.12.1 release.

[abdennour]

It happens with me when running docker build where the base image was upgraded from FROM node:10-alpine to node:11.1.0-alpine.

Since I want to keep node 11 as the base image, I had to migrate my commands from yarn to npm.

[PutziSan]

I can confirm this happens under windows 10 with yarn 1.12.3 and node 11.1.0.

When I changed node-version back to 8.12.0 everything works without problems (or "trouble"). (I changed the versions via nvm-windows)

[rexkenley]

Windows 10, Yarn 1.12.3, NodeJs 11.1.0

What solved my issue was to increase the network-timeout to 60 secs.

[worldkk1]

I got the same error.
try npm config set registry=https://registry.npmjs.com/
it's work for me.

[vipulkumarsviit]

I was getting this error too. Rerunning the install with --verbose told me that it was "https://registry.yarnpkg.com/@expo/traveling-fastlane-darwin/-/traveling-fastlane-darwin-1.7.1.tgz the was causing the issue.

I tried visiting it in Chrome - sure enough, it downloaded - but then hung for a while at 100%. This usually happens when it's getting scanned. It _is_ quite a big tarball.

Lo and behold, disable Windows Defender real-time scanning and it works fine. It seems that if the virus scanning takes too long, Yarn chalks it up as a network problem.

TLDR: if you're on windows, try disabling real-time scanning and reinstall.

if you have issue

info There appears to be trouble with your network connection. Retrying...

i think you must configuring proxy
Use these commands ;

yarn config set proxy http://username:password@host:port
yarn config set https-proxy http://username:password@host:port

[the94air]

Changing registry seems to fix the issue for me:

yarn install --registry https://registry.npmjs.org

[RehabHussein]

I had the same problem in Windows and increasing the network timeout fixed it for me ! Thank you

[jklemm]

Same error. To solve, just erase the yarn.lock and run yarn command to recreate.

I ran into this issue yesterday, I cannot retrieve @material-ui/icons with yarn. I've tried the suggestions on this thread (network timeout, changing registry, remove node_modules and install again). However, installing with npm completes successfully.

If I visit the package URL directly, I can download it in my browser (and is only 1.2MB). Not sure what's blocking yarn.

[darkliquid]

Having this exact same issue with @material-ui/icons too. Nothing on either windows native yarn, or yarn running under wsl with or without network timeouts extended or integrity checks disabled seems to make any difference. Likewise I can simply download the files in the browser fine. Npm installs fine.

[todorstoev]

Removing @material-ui/icons from packages also resolve issue for me.

[mustaphaturhan]

I got exact same @material-ui/icons issue today. I deleted everything related with yarn in my project to solve this issue by doing rm -rf node_modules yarn.lock in bash. I ran yarn command after delete process is done. And issue was solved, I didn't see any errors after that.

[callmeberzerker]

yea @mustaphaturhan i had exactly the same issue today with @material-ui/icons as well... solved it the same way. :\

[m0o066]

removing ~/.yarnrc works for me

[PutziSan]

I think it just happens when the packages are very large or contain a lot of files (I also often see this message for the icon-packages of fontawesome).
Maybe a time limit is not the best way to check this. You could also do a 1kb-test-ping if the time limit is exceeded. Only if it fails you can actually do a retry, otherwise everything is okay, it just takes a bit longer.

[gknapp]

I still can't install install @material-ui/icons. I've remove node_modules, yarn.lock and run yarn cache clean, upgraded node to 10.16.0 and re-installed yarn. I'm on Windows 10.

One oddity, I could install all packages successfully if I cloned my project into a temp directory. The problem manifests in my workspace. I've looked for hidden files, couldn't see any. Still seeing:

Error: https://registry.yarnpkg.com/@material-ui/icons/-/icons-4.2.1.tgz: ESOCKETTIMEDOUT`
  at ClientRequest.<anonymous> (C:\Users\<user>\AppData\Roaming\nvm\v10.16.0\node_modules\yarn\lib\cli.js:130217:19)

Switching my project over npm.

[ezfe]

I've just had the same issue because somehow npm configured my proxy to ready apple.asd (unsure how, I did not do this). I did yarn config list and identified the setting that way. After removing, it worked.

[adabru]

If you have ip6-only network and the error occurs, you can try to workaround with adding

2606:4700::6810:1723 registry.yarnpkg.com
2606:4700::6810:1723 registry.npmjs.org
2606:4700::6810:ab63 yarnpkg.com

to /etc/hosts. You can get the ip6 with nslookup registry.yarnpkg.com. https://github.com/yarnpkg/yarn/issues/6031

[juliehive]

I had a very similar issue that was resolved by uninstalling and reinstalling node/npm

[ryu9827]

For me, I just remove both npm and yarn lockfile and run yarn install again

[zeevl]

Also had problems with @material-ui/icons on windows 10. Disabling real time protection from windows defender as @stewartml suggested did the trick.

[Adamkaram]

you can do
npm config rm proxy
npm config rm https-proxy
for remove any proxy
or if u want to use proxy u can do this
$ yarn config set proxy http://my_company_proxy_url:port
$ yarn config set https-proxy http://localhost:3128

or to make timeout 600000 maybe z file is big
yarn config set network-timeout 600000 -g

or do this if you want to keep the default timeout as it being
yarn add --network-timeout 100000

[xdkaka]

rm -rf /Users/xxx/.config/yarn/global/yarn.lock
then done

[ibragimOnlinesup]

solved by reboot :D

[sapeyes]

In my case, it was working by turning off AdGuard and Windows Defender on Windows 10. I also use this command.

yarn install --network-timeout 1000000

[huangguorui]

我仍然有这个问题。增加网络超时无济于事，@ suhailgupta03的代理删除也无济于事。现在，yarn不会安装，添加或做任何事情。我已经通过三个不同的网络进行了尝试。

Adding time didn't solve my problem. It still existed and I didn't solve it

[jimmyyem]

npm config rm proxy
npm config rm https-proxy

I hope the above commands will help.

[huangguorui]

There are still problems.

Network speed not acquired correctly.

[allthesignals]

Why is this closed? This continues to be an issue. Why? It has plagued my machine for weeks now, across many projects.

[ezfe]

@allthesignals Most of the issues reported here are various configuration issues. I myself had a misc. configuration issue, for example. Things like incorrectly set proxies are a big one. There's no way to easily resolve this since it's a catch-call for weird internet problems.

[allthesignals]

Okay, thank you @ezfe. I do think the info message is inaccurate for some people's situations.

For example:

I think it just happens when the packages are very large or contain a lot of files (I also often see this message for the icon-packages of fontawesome).
Maybe a time limit is not the best way to check this. You could also do a 1kb-test-ping if the time limit is exceeded. Only if it fails you can actually do a retry, otherwise everything is okay, it just takes a bit longer.

[elhamzaouiaymen]

I had hhe same issue. Actually I was running the command while a streaming video process is running (netflix). So I just paused it then I ve retried again and it works without even setting timeout to infinite value.

[rbiggers]

I had the same issue, but I didn't notice it until I deleted the node_modules directory in my local repo.
Then I started seeing the network error. Evidently there was an old package in my package.json that was referencing a package that was behind the company firewall (I was also not on the VPN). Once I deleted the offending package from my package.json everything worked correctly.

[jetonk]

I had the same issue, my solution was updating the node version and the issue disappeared.

[allthesignals]

This again.

verbose 0.942 Performing "GET" request to "https://registry.yarnpkg.com/rxjs/-/rxjs-6.5.4.tgz".
verbose 1.047 Performing "GET" request to "https://registry.yarnpkg.com/rxjs/-/rxjs-6.5.3.tgz".
[##########################################################################################] 950/

It just hangs at these last two requests.

[TedSean]

I am having this issue too on yarn version --> 1.15.2

[the-turk]

You shouldn't close issues unless you solve them or inform people about what could go wrong.

[rotelando]

I ran yarn while building my docker image and had the same issue as mentioned. Restarting the docker daemon solved it for me.

[mirague]

rm -rf /Users/xxx/.config/yarn/global/yarn.lock

@xdkaka Thanks, that worked for me! Seems that yarn.lock had some old private repository urls set.

[TheCoderSingh]

--network-timeout 1000000 fixed it for me but took a long time to install just one package - @material-ui/icons

[Liqiankun]

In my case, I deleted yarn.lock file. Then it works well.

[phyolim]

I guess there isn't "one size fit all" solution for this error. In my case there was a cyberark process on my i5 computer hogging all the resources. I force ended that process and the error went away. I think it has to do with antivirus. I'm sure it will come when i restart the pc. Such a waste of time working on windows.
