Cookie and header size error.
Certain boorus are unable to load due to an error. Request header or cookie too large giving a 400 error.
Which engine are you using?
I have the 400 error too large cookies and header for Allthefallen it’s using Danbooru but make this error since one or two weeks.
Since a new DDoS protection AllTheFallen is fully dead atm. But regarding this specific isue: Every time I got this error all I need do was wipe the cache through the settings menu with the remove all cache feature. Than relaunch the app and re-accept the new cookie. And it works fine again.
This seems to happen periodically after enough cookie resets. the header keeps gradually getting bigger untill it breaks. Clearing the cache will reset it again and have it work again.
Yet at the moment AllTheFallen does not work at all due to a new DDoS/Bot protection that needs user interaction. I openen an issue for this allready.
