I un-subscribed from a mastodon.social user. I was under the impression that something was wrong because I didn't received any status from the given user. Now when I try to re-subscribe I get a "internal error" on my !gnusocial server. Does someone heard something like this before? Anything I could do? For example check a specific database tables if there are still some information stored about the mastodon.social user? Maybe @mmn or @gargron knows more?
