Description

When attempting to log in via Discord or Google OAuth2, it opens up the other site and shows the authorization consent screen. Upon clicking yes, I'm redirected to my callback URI but its a big error 500 with no error message/text or explanation. Looking in the gitea logs, I see these messages:

...eb/routing/logger.go:102:func1() [I] router: completed GET /user/oauth2/discord for [REDACTED]:34454, 307 Temporary Redirect in 2.0ms @ auth/oauth.go:849(auth.SignInOAuth)
...rs/web/auth/oauth.go:939:SignInOAuthCallback() [E] UserSignIn: could not find a matching session for this request
...eb/routing/logger.go:102:func1() [I] router: completed GET /user/oauth2/discord/callback?code=[REDACTED]&state=[REDACTED] for [REDACTED]:34470, 500 Internal Server Error in 2.9ms @ auth/oauth.go:888(auth.SignInOAuthCallback)

I tried to hunt around the open issues for similar things, but #5005 and #5551 don't seem to be my issue. This occurs regardless of DISABLE_REGISTRATION setting and attempts after the first still return the same 500 result.

The Github OAuth2 does work after the first time (which fails with a 500). But nothing I've tried manages to get the other two working. I've checked and double-checked my client id and secret as well as the callback URIs. Any information you might need I'm happy to try providing.
