Sometimes it's work, but for mostly manga the reading and downloading function failed.
A screenshot here:

I tried to wipe cache, cookies, change IP, change DNS, not working at all.
I specify that it's working on website.
If you found a method for debugging extension please say it, it'll be faster.
Looks like they're using a new format on the web which is like a webtoon reader. Maybe that's what's breaking it.

Yes after test it's effectively that. Only webtoons have problem.
I've test with :
not working :
working :
i don't know what's a difference between the next webtoon.. but some one don't work
Seems that they removed the scrambler o_o

chapter 89 is scrambled ----- 90 isn't (released yesterday)
Japscan usually scrambled the chapters of mangas that they bought the official french simulpub version (like Eden's Zero)
I've searched for another manga and it's also the case of https://www.japscan.co/manga/fuuka/ (chapter 175 is scrambled and 176 isn't)
Maybe it has something to do with that issue?
EDIT: Same as https://www.japscan.co/manga/crazy-zoo/, https://www.japscan.co/manga/vertical/. Last chapters aren't scrambled.
They definitely changed something for that kind of manga (official version, not scantrad).
EDIT 2 : forget about that. It was temporary.
The problem appears also inside chapters, you can see it, if you use the download function
So ? How can it be solved ?
Is there any method/solution given for the problem? I'm not sure to undrerstand everything.
Allow me to explain my issue in french馃槄馃槄
Le probl猫me c'est qu'en ce moment aucun de ceux de Tachiyomi ne fonctionne. Certains de ceux de Tachiyomi Device version fonctionnent encore, notamment Vampire Knight. Par contre Rosario Vampire II ne fonctionne ni dans l'un ni dans l'autre. Et c'est arriv茅 tout 脿 coup comme 莽a alors que je finissais de lire le tome 6馃槷馃槷
The issue doesn't only happen with webtoons, it happens with everything (Boku no Hero Academia for example)
It doesn't work for me either, suddenly it stopped working, for my part it was prison school that stopped working (and all the others after) Still no solution?
It stopped working for me also.
On desktop, i'm using hakuneko to download from various sources. among them is japscan, which is working. The only glitch is that i have to setup a relatively big timeout for it to keep downloading from japscan....
Maybe it's interesting to see how they're dealing with these recurrent japscan issues : https://github.com/manga-download/hakuneko/issues?q=is%3Aissue+is%3Aopen+japscan
I found that chapters doesn't load on the webview, when firefox or chrome load it successfuly. Perhaps Japscan detect the browser used and act accordingly.
Exemple with a screenshot:

Is any dev available for this issue 馃槩 ?
Same for me. It works, then suddenly it doesn't work. I hope you guys will find a solution to this issue, because we french only have this source to read anything
Well - you'll probably want to request better sources, then.

Unfortunately not. That's why I hope someone will come up with a solution
Unfortunately not? Do you mean better sites simply don't exist?

Not to my knowledge. I only know Scantrad but it never worked on Tachiyomi

Japscan is unfortunaly the biggest aggregator of french sources. The website is full of ad and it don't mention the translator. But he is the biggest though.
I hope that someone can somehow find a solution 馃槗
Any solution or alternative ?
Same problem here :(
In my case it was still working 2 days ago but it's broken since today
Unfortunately, Mangakawaii and other French sources referenced in tachiyomi only give access to a few chapters but rarely the whole mangas...
Still got the problem, perhaps it can be fixed by changing the user-agent used to made the request? It's clear that webpages doesn't provide the chapter images under some circumstances. They probably want to block automatic pages donwload by checking that the request has been made by a legit browser.
Maybe it can also be a JavaScript challenge?
Has the problem been fixed in the latest version? If not, which other apps do not have this problem?
@LeavesEatingCow The problem is still present on Japscan ver1.2.20
Manga tested:ah my goddess (chap 307)
I hope that the problem will be solved quickly. It's already been a few months since we can no longer read manga on tachiyomi.
Additional information:
Mi Manga Nu app( https://github.com/raulhaag/MiMangaNu ) loads chapter(domestic na kanojo chap 135) but they are broken
I found an alternative. I know it is scanned but it seems to work very well. I checked my hero and attack on titan so far and they have the latest chapters avaliable.
