@silverpill It's.. complicated. For various reasons, Forgejo needs to explicitly allow various remote server software to interact with it. That list currently includes forgejo, gitea (for historical reasons), mastodon, and gotosocial.

Forgejo should reply with something nicer than an 500, though - I'll look into that!

Eventually, I want to remove this server software limitation (it's legacy code; I understand why it was done so, but I think it's the wrong approach), but that will take a little longer.
