404: couldnt_find_community

After search wouldn't show a bunch of communities, I started manually just editing the URLs and then I ran into a new set of problems.

If I go direct to the lemmy instances they work, but via this instance, I'm getting a bunch of 404s.

The list

Apologies, for some reason I seem to be finding all the bugs.
