Desktop: Client fails after resuming laptop

[pzwahlen]

I'm testing the latest 2.5 since a couple weeks, currently running "Nextcloud-2.5.0.0-Debug-20180710.exe" on Windows 10 Enterprise x64 1803. It's running against 13.0.4 on the server side.

When laptop resumes from either sleep or hibernate, client shows a red cross in the tray icon. Stopping and restarting the client solves the problem.

Nextcloud_sync.log and .owncloudsync.log do not show anything useful.

I'm also referencing #324, even though it relates to the stable 2.3 build which has been working fine for me, up to the latest 2.3.3.1.

Finally, I'm not using any of the new features (like E2E encryption).

Please let me know how to extract useful logs, happy to do so.

[pzwahlen]

While trying to recover from this situation, I usually either exit the client or double-click on it. This generate the following crash logs:

Have the same issue on Windows 7 64 bit, daily build 2.5.0git from July 11.

After resuming hibernation the tray icon of the client shows a red cross and the client window can't be restored.

Windows notifies me of problems with this application and only allows me to terminate the client.

After this I can start the client anew.

This behaviour was different some time ago with an older daily 2.5.0 build. I could restore the client and it showed unrecoverable error messages inside it.

[pzwahlen]

Yesterday I made a new test with the latest nightly build for Windows (Nextcloud-2.5.0.61457-daily-20181009.exe).

This issue is still present and after wake-up, the client was showing a red-cross in the tray area. Left-clicking would open the GUI and a red banner mentioned a socket timeout.

Trying to right-click in order to reach the menu and exit the client didn't work. The icon simply disappeared which I think is a sign of the client either crashing or at least exiting in a strange way.

I still couldn't find any useful log.

Server is now running 14.0.1

324 looks similar but on the "stable" client, which for me is working like a charm and perfectly survives sleep/resume.

Any way to help further troubleshoot this issue ?

[pzwahlen]

A couple days ago I installed 2.5.0-rc1 and so far I haven't seen the red cross. Fingers crossed.

The NextCloud Desktop client for MacOS also stops working when my laptop is resumed from sleep. Even if I pause and resume the sync, it doesn't recover. It looks like I have to manually go into the settings, click on the Account button, and click on Log in. Shouldn't it retry?

My Nextcloud server is running 13.0.8.

Same issue here on my Windows 10 system. After hibernate I do get sync error from nextcloud client. Only solvable via restart of client.

[lamba84]

Same issue here, Windows 8.1 64 bit. Client version 2.5.0v2.5.0 (build 20181112), server version 14.0.4 on Debian stretch

[rednaxela-work]

For me the problem has disappeard with one of the later nightly versions prior to the 2.5.0 client release.

So I'm not experiencing such issues anymore (Windows 7 64bit and Windows 10 64bit).

[pzwahlen]

The situation has greatly improved with 2.5. I sometime had the client crashing on me when trying to open the UI (with a QT app crash event log), however since 2.5.1 this seems to be fixed. I'll open a new issue if I can reproduce this crash.

Thanks for the hard work!

[tinola]

Version 2.5.1 (build 20181204) - same issue - red cross after resume from sleep :( Restart client is necessary. Windows 10 x64 (1803)

[PiotrIr]

Same issue with 2.5.1 on all Windows 10 machines.

[fzieris]

Same here (using Windows 10). It is not limited to hibernation, though. It's the same issue when I connect to or disconnect from a VPN network (using Cisco AnyConnect, in case that matters to anyone). It looks like any change to the network adapter throws the client off the rails.

[rwilliamsit]

Same issue here, 2.5.1 client / Windows 10

[Exception0815]

Same issue with Version 2.5.1final (build 20181204), Win10 1709 German.
By the way I have Comodo Firewall installed but the logs are not showing any entries.

NC client log:
QNetworkReply::NetworkError(UnknownNetworkError)
[OCC::WebFlowCredentials::stillValid "Der Zugriff auf das Netzwerk ist nicht gestattet."
[OCC::PropfindJob::finished PROPFIND of QUrl("*") FINISHED WITH STATUS "UnknownNetworkError Der Zugriff auf das Netzwerk ist nicht gestattet."
[OCC::PropfindJob::finished not successful, http result code is 0 ""

[Niondir]

Same here: 2.5.1 on Windows 10. This is pretty annoying.

Is there any workaround that does not include restarting Nextcloud?

[rwilliamsit]

I ended up downgrading my client to the one that was out before 2.5... I think it was released Dec 2017? I’m not at my desktop right now. I got tired of this bug and also another regression I noticed where the 2.5.x client tries to sync files that are still open for write which results in an error that it failed to sync...

[Haplo164]

Same issues, It seems to happen when windows stops network services.

[Exception0815]

As a workaround create a Powershell script with following two lines, and run it automatically everytime you wake your PC by using a scheduled task. It will then restart the Nextcloud application:
Stop-Process -name nextcloud
Start-Process -FilePath "C:\Program Files (x86)\Nextcloud\nextcloud.exe"

Create then a new scheduled task, enter following XML code as a trigger:
<QueryList> <Query Id="0" Path="System"> <Select Path="System">*[System[Provider[@Name='Microsoft-Windows-Power-Troubleshooter'] and (Level=4 or Level=0) and (EventID=1)]]</Select> </Query> </QueryList>

To run a PS script as a scheduled task see https://community.spiceworks.com/how_to/17736-run-powershell-scripts-from-task-scheduler

[noja11]

I'm also experiencing this issue. When the laptop system sleeps/hibernates, the client crashes. Running Version 2.5.1final (build 20181204).

After a few tests however, I can see that the service has stayed up once I un-ticked "Launch on system startup" under the settings tab. Of course I have to remember to launch the client on full reboot, but as this is a laptop, that happens less frequently than sleep/hibernate.

*edit - totally forgot that I can add nextcloud to the list of programs that Windows starts on boot. Hopefully this work-around solves my problems.

[pgpbj]

Same issue for me. Sleeping/Hibernating Windows 10 will cause the 2.5.1 client to fail after resuming. Restarting client will fix the failure.

Trivial to reproduce, yet still at triage stage after 7 months?

Will experiment with the suggested workarounds above...

[Niondir]

Just tested with "start on boot" disabled. Does not help with my machine.

[noja11]

Just tested with "start on boot" disabled. Does not help with my machine.

Sad that's not working. I've noticed on my end, that if I just put my laptop to Sleep, it'll wakeup and the client will work just fine. However, if it ends up closed for too long and moves into Hibernate, I'm still getting the crash.

[jprokosch]

Same issue for me in Windows 10 and Nextcloud client 2.5.1
Annoying and systematic problem...
Hope to get a fix soon as possible !

[pgpbj]

I downgraded to version 2.3.3.1 (from https://download.nextcloud.com/desktop/releases/Windows/) and, so far, the problem seems to be gone.

[NiklasOlofsson]

Same here. Windows 10. My main computer waking from sleep, white X, red background on NextCloud client icon. Close and reopen the client will fix it.

Version 2.5.1final (build 20181204).

I added some more infos on https://github.com/nextcloud/desktop/issues/324#issuecomment-483336116

[elforesto]

I manually updated to 2.5.2 and the client now behaves as expected on resuming from sleep or hibernate.

[ThomGr]

Still see almost always a crash of the client (2.5.2, build 20190319, git 56c905, Windows 10 1903) when resuming from hibernate on a Lenovo T480s. Any progress on this? I would be happy to send debug information or a crash dump.

[misch7]

Have you also tried our latest release 2.5.3 ?
https://download.nextcloud.com/desktop/releases/Windows/Nextcloud-2.5.3-setup.exe

And if this still happens with 2.5.3, would you try one of our current daily builds?
https://download.nextcloud.com/desktop/daily/Windows/Nextcloud-2.5.3.5732-daily-20190820-Release.exe

Since 2019-08-18 we're compiling against Qt 5.12.4 so there's a chance it might have fixed the issue accidently ;-)

I'm curious how it turns out.

[ThomGr]

interesting, 2.5.3 seems to solve the issue. I will monitor it and try a daily build should the problem come back.
BTW, I checked in the client and it did not offer any updates, so I did not look on the website. Thanks for mentioning the latest version!

[stale[bot]]

This request did not receive an update in the last 4 weeks. Please take a look again and update the issue with new details, otherwise the issue will be automatically closed in 2 weeks. Thank you!

[ThomGr]

in contrast to my earlier post, 2.5.3 does _not_ solve the issue. The client keeps crashing after resuming from hibernate state, not from power saving state.

[misch7]

Could you also try our recent 2.6.0 release build?

https://download.nextcloud.com/desktop/releases/Windows/Nextcloud-2.6.0-setup.exe

Qt 5.12.4 had a lot of issues with UI and crashes so perhaps our upgrade to Qt 5.12.5 in the last release solves it - fingers crossed

[ThomGr]

no change with 2.6.0

[ice954pw]

Same Issue with 2.6 as well

[tanfwc]

same issue on my end too. 2.6 on Windows 7

[ice954pw]

Fixed on latest build, 2.6.1

[ThomGr]

installed 2.6.1 today, but the issue is not fixed for me

[adaigre]

I'm on archlinux and my client fails after sleep.
I don't have a systray/notification icon (I'm using Gnome) but the client only seems to freeze.
After a few seconds, the client close himself.

I've also got a Windows machine who seems to have the same problem.
My Nextcloud installation was recently moved to a new server but no change ...
I'm using Debian 10 with nginx, php-fpm (7.3) and MariaDB.

Sane problem with version 2.6.4stable-Win64 on Win10 1909. Need to restart after resume from power saving.

I also need to restart the Nextcloud client on MacOS since several versions every time after sleep mode was used. Current version: Version 2.6.4stable (build 20200303). MacOS Catalina

I ran the client with the log option. See the last lines of the log and also what I received on the terminal:

PS: I am using the Nextcloud service of Hetzner. Could the problem be server related? I cannot imagine, but just mentioning in case other Hetzner customers are here.

[godfuture]

After standby I see a red icon with white X. NC client seems to be started, but sync in background is not working...even icons in windows explorer are green. I have to restart the client to bring it back.

All sync folders show the same message:
"Beim Öffnen eines Ordners ist ein Fehler aufgetreten. Der Zugriff auf das Netzwerk ist nicht gestattet."

Win10 x64
2.6.4

Edit: I hesitated to report this issue, because I thought: "No, it is impossible that you face such a basic error for a software that is used on millions of clients. It has to be my computer..."

[amelekhin]

I can confirm that this issue is still reproducible on Windows 10 Home 2004 and Nextcloud 2.6.4. Every time my laptop hibernates or falls asleep, the Nextcloud client stops working. Only restarting the app makes it work properly. Unfortunately, I don't have experience in C++ to debug it by myself, so I hope someone can take a look at this issue. It's quite annoying and two years old already.

[weeheavy]

For me, the bug is reintroduced with 2.6.5, it was working flawlessly with version 2.5.2. After hibernating, client shows a red cross, when clicking the tray icon it goes away/crashes. After starting the Nextcloud client again, it works until the next hibernation.

[gregholst]

I am on MacOS Catalina and since the new version it's the first time that NextCloud Desktop Client does not crash due to hibernation since I am using it (roughly 1.5 years). I guess the problem became "Windows-only"

[nightspotlight]

on version 3.0.1 for Windows the desktop client stopped crashing, but still after resuming computer from hibernation the client is unable to resume synchronization due to error "network connection is disabled" (Доступ в сеть отключён). Forcing synchronization doesn't help. how can I help debug this?

[q-wertz]

I am on MacOS Catalina and since the new version it's the first time that NextCloud Desktop Client does not crash due to hibernation since I am using it (roughly 1.5 years). I guess the problem became "Windows-only"

On MacOS the crash happens again with the newest version
NC Client Version: 3.0.1git (build3355)

@gregholst can you confirm this?

Unfortunately, I have to confirm that within the newest version the problem was re-introduced on MacOS

[jameskimmel]

If have the same problem under Windows 10 with Version 3.0.1.

It is very annoying and should be very high on the priority list IMO! If offer nextcloud to non tech savvy friends and parents and it is hard to explain to them, that they should pause and resume every time they open up their laptops.

[kusmi]

Same problem on 3.0.2 Mac. When Laptop is put to sleep or has no network connection for a while (e.g. out-of-house or in locations with open WiFi networks which redirect all web-requests to a login/register page) - but then has internet connection again: It will often not recover and stops syncing altogether.

It often still shows the "checkmark" icon in the Dock (so a normal person would assume all is synced) - but only a restart of the nextcloud client will recover.

[robinedmunds]

I've started experiencing this issue on Windows 10, 1909. Nextcloud client v3.0.3.

On resuming from sleep, the client's tray icon is red, no syncing occurs but the app is responsive.

Pause-resuming syncing does not fix the issue. Closing and relaunching the client restores normal function.

[barry-luijten]

Problem came back in 3.0.3 and is still present in client v3.1.0.
See also multiple reports in #865

[heziegl]

workaround that worked for me was to use exe-installer instead of msi-installer.

Isn't it duplicate of #482 indeed?
