Linking Github account fails, redirects to homepage #2366

Comment

in security settings, if I click "link account" and choose "Github", then click "authorize" in the oauth prompt:

the oauth authorization succeeds, but I get redirected to codeberg.org and linked accounts is still empty:

this appears to only affect my account, as a friend was able to successfully link their github account to their codeberg account. in their case, it redirected from the oauth page to the security settings, and now shows github is actively linked in those settings

Do you have any browser extensions that could potentially remove query strings from URLs? Could you try doing it on another browser/device?

I've tried it on vivaldi, chromium, and firefox, regular and private browsing in each. firefox and chromium have no extensions.

in my latest attempt, I tried to click the redirect manually instead of waiting for it to navigate automatically, and got this (url: https://codeberg.org/user/oauth2/GitHub/callback?code=<hex string>&state=<uuid>):

I'm seeing the same problem. For what it's worth, the codeberg account was created after a number of issues created by the github account were migrated to codeberg. Also the codeberg account was originally created by signing in with GitHub.
