Invalid_request when setting up server

Attempting to open fx server redirects to the login page and after putting in the code it redirects me to a different site which only has to word on the screen “invalid_request”. If anyone knows a fix - please help me out

Having the same issue, however, this is happening when attempting to log in through CFX on any site, including Tabex. I can log in fine on my phone to the same websites, but on my PC, it comes up with Invalid_request.

Figured it out. Works for me atleast but try logging in on an incognito window. If that works then just clear cfx.re browsing data, cache and cookies
