Tachiyomi-extensions: ReadComicOnline/KissManga/MangaHasu: HTTP error 503/Duktape error

[Radio-9]

Unable to access extension ReadComicOnline, due to HTTP error 503
ReadComicOnline version: 1.2.5
https://readcomiconline.to/

Tried this in both Tachiyomi 0.8.1, Tachiyomi r1469

[leoteesh]

Also getting the same error for mangahasu

[QuietusWolfe]

Same error with Kissmanaga on 0.8.1

[TheWrightStuff1994]

Having same issue as well!

[Neshura87]

Same error on Kissmanga version 1.2.9 using Tachiyomi 0.8.1. Tried clearing cookies and opening kissmanga in the browser, reinstalling the extension and restarting my phone but did not work

[hXtreme]

Try installing the My Manga Reader CMS extension it should provide a source called "Read Comics Online" which I believe is the same source as "ReadComicOnline". While this is not a solution it should allow you to read your comics till someone patches it.

Or you can just migrate sources.

[CarlosEsco]

@hxtreme it's not. Just similar named

[DitFranXX]

It's CloudFlare issue, They update JS Challenges again.

Everything with CF can cause a 503 error.

[ThomasCapella]

I'm getting this too. I just installed the latest version and it's doing this so updating won't fix it.

[pseudophotographer]

Having same issue, some days ago we had the syntax error but it got patched. Do we have any news about the http error?

[yasnil03]

Also the same with Mango: HTTP error 503

[CarlosEsco]

fixed in latest dev tachiyomi. Hopefully stable released soon.

[Fokkusuteru]

Same issue. I downloaded both the dev and the stable versions. The same error seems to come for both on kissmanga. Other sources work fine

[buzmeg]

R1471 is still returning 503. I am still seeing it on other sources too.

[MerradOklom]

@buzmeg which source? I tried with Kissmanga and it's working fine

[Fokkusuteru]

My kissmanga isn't working. Rest of all sources are working fine. Errors alswyas seem to be on kissmanga with me

[TheWrightStuff1994]

ReadComicOnline.to and Kissmanga are working for me, don't know why it isn't working for others?
And it the dev version that im using

[Dial-upMan]

Error has changed from a 503 error to: "com.squareup.duktape.DuktapeException: ReferenceError: identifier 'atob' undefined". No clue if this is just me as well as if it's important either.

[El-Gavy]

@Dial-upMan same here using mangahasu.

Forgot : r1469 & mangahasu English 1.2.4

[pseudophotographer]

Having the same error: "com.squareup.duktape.DuktapeException: ReferenceError: identifier 'atob' undefined".

[Neshura87]

Same new error: "com.squareup.duktape.DuktapeException: Reference Error: identifier 'atob' undefined" using Kissmanga as the source (using latest stable: 0.8.1 and Kissmanga 1.2.9)

[pawrawr]

Getting also the new same error. "com.squareup.duktape.DuktapeException: Reference Error: identifier 'atob' undefined" using Kissmanga as the source (using latest stable: 0.8.1 and Kissmanga 1.2.9)

[joeoh1359]

On r1471:

Going directly to KissManga seems to get it stuck on the 5 second challenge, so the squareup.duktape 'atob' issue may be a KissManga thing.

For those still getting the 503, did you clear your cookies in the app?

EDIT:
Mangahasu seems to also fail with the 'atob' issue when trying to actually read anything.

EDITx2:
Seems like it's cloudflare again, since cloudflare's protection shows up for Mangahasu when you go into a chapter. Oddly enough mangahasu seems to work fine (in browser), but kissmanga is just straight up broken.

[ThomasCapella]

I'm using F-Droid. Will it update if I'm using the dev repository?

[reddeimon]

Same problem with version 0.8.1- r1471

[barracudaman]

I'm having the same issue. I keep on getting "com.squareup.duktape.DuktapeException: ReferenceError: identifier 'atob' undefined" every time I attempt to open the ReadComicOnline (V 1.2.5) extension. I've tried to get it to work on both 0.8.1 and r1471. If you could patch this, it would be much appreciated.

[joeoh1359]

I'm no longer getting the atob error now (v0.8.1 r1471).
Wondering if it's because I switched networks or if it was on cloudflares end.

[barracudaman]

I'm no longer getting the atob error either. Instead, I am getting a 503 error.

[Peuuuur-Noel]

Duktape exception is an issue due to CloudFlare code changes that happens sometimes. They are maybe testing some changes. Troubles are gone for now, but can come back anytime.

I put this here in case it could be used.
Here are changes that I saw and break the CloudFlare interceptor in the base app (https://github.com/inorichi/tachiyomi/blob/master/app/src/main/java/eu/kanade/tachiyomi/network/CloudflareInterceptor.kt).

• JS and DOM/HTML evaluation needed. Duktape Android can't handle this.
• New variable k with the ID to a hidden div with content than need to be eval (return an integer).
  Example of line with k var: t = t.substr(r.length); t = t.substr(0,t.length-1); k = 'cf-dn-zjAaF';
  I didn't keep an example of the hidden div :/ But it's an operation of binaries like that: (!+[]+!![]+!![]+!![]+!![])
• Obfuscated code does call to DOM like this:
  atob("ZG9jdW1l")+(undefined+"")[1]+(true+"")[0]+(+(+!+[]+[+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[+[]])+[])[+!+[]]+(false+[0]+String)[20]+(true+"")[3]+(true+"")[0]+"Element"+(+[]+Boolean)[10]+(NaN+[Infinity])[10]+"Id("+(+(20))["to"+String["name"]](21)+")."+atob("aW5uZXJIVE1M")
  We get this once eval:
  document.getElementById(k).innerHTML
• Function atob() -> base64 decode. Not supported by the version of Duktape Android used?

[pawrawr]

No more atob error, 503 error is the thing that I got now.

[arkon]

Thanks for the info, @Peuuuur-Noel.

Function atob() -> base64 decode. Not supported by the version of Duktape Android used?

Makes sense. Duktape is an implementation of ECMAScript, and atob() is part of the browser window API.

[Neshura87]

Atob error gone 503 is back, hope next stable with the fix comes out soon

[pawrawr]

No more atob error, 503 error is the thing that I got now.

[DitFranXX]

Try latest dev build.

[yasnil03]

How?

[aqeeliz]

How?

Try https://tachiyomi.kanade.eu/latest

[thomasprat49]

It's working for me with the latest dev

[El-Gavy]

Same here, r1474 solved it ! Thx !

[Reiriin]

I tried r1474 and KissManga is still not working...

[rachzps]

presents the following error

SyntaxError:parse error line(1)
entension ver. 1.2.9 kissManga

[AedricVinters]

I tried r1474 on Thursday and it wasn't working at the time. Not sure what I was doing wrong or what might have changed but r1474 and KissManga extension are working for me as of right now.
Thanks!

[matryosha]

Is the patch going to stable?

[lenyer21]

Why is KissManga isn't functioning It says http error 503 ...what should I do plsss

[demir923]

I also have an http error 503 on Japscan (French source) even with the New update

[leoteesh]

Getting ducktape error on mangahasu after the new update. Same error with rev version

[CarlosEsco]

Cloudflare change again
