nhentai not working

[Andor233]

nhentai metafile is not working, and after doing some debugging I found that it is 503.

Is that a Cloudflare problem, or just for me?

I have a proxy(clash) on my router and it works well. No problem for ehentai or else

nhentai is using cloudflare with the javascript challenge enabled, causing the problem.

Maybe a possible solution could be to create a login-plugin using the cloudflare cookies (depending on how long they're valid), so the js challenge gets skipped. I'm currently testing how long the cookies are valid, but as I just started today, it'll take a while I guess.

So with the cookies will work? I used to want to try it but I am not familiar with Perl and HTTP.....

Seems so, yes. Without cookies I wasn't able to perform a test request using curl to (as an example) nhentai.net/api/gallery/177013, but with the cloudflare cookies (csrftoken and cf_clearance) as well as the matching User-Agent from your Webbrowser I could successfully access the api.
The cookies set in my browser have an expiry set for 1 year, but as the default expiry for cloudflare is 30minutes, the question is if they're really 1 year valid, which would be nice.

Will you release the login plugin? (By the way I want to know the reason of choosing perl)

Will you release the login plugin?

I'll try to create one this weekend and if it works (and the cookie expiry time is not too short) I could make a pull-request to get it merged

As I'm just some random guy that discovered this software a few days ago I am not able to answer that question :(

Making a login plugin for cloudflare would be a nice solution! (I'm guessing said CF cookies are tethered to the website that issued the challenge so the plugin would initially be NH-only, but that could be improved in time with a few backend changes)

It's likely the cookies are only valid 30 minutes no matter what, but if setting their expiry to 1y works it'd certainly make that solution much more usable.

Fun things are fun!

I didn't change the expiry, it was added just like that. Right now, the current cookie is still valid (~17 hours) - so maybe it really is a year valid.
I'm currently modifying the EHentai.pm for nHentai, but I guess it does require a modified nhentai-metadata plugin too, as it has to use the nhentai-login data (right?)

[Difegue]

Awesome then!
Theoretically, there's no changes to make to the nH plugin except making it dependent on your newly-created login plugin. (depends on whether it's correctly using the mojo::useragent object provided by lrr_info for all its network requests. )

@Pheromir 's login plugin has been added into the base pluginset of the server and should allow you to use CF cookies to get nH to work again. 🍾
