If I try to follow an account on my new instance at https://mastodon.openpsycholgy.net/ from my mastodon.art account, I get an error:
503 Remote data could not be fetched
which gets displayed. This seems to be something that has to do with some configuration issue I’m having, as I am seeing errors, and things getting linked to https://mastodon.datsemultimedia.net/ which doesn’t exist.
I’m not sure where this is set, and it looks like at least one place things are set correctly. I’m not really sure what might be helpful with figuring this out.
It does seem to have a number of different symptoms, as avatars aren’t displaying correctly so somewhere I’ve got something setup incorrectly. I just can’t find it.
