This includes all of the @beehaw.org communities I tried to subscribe to. It also includes all BUT ONE of the @lemmy.world communities I tried to subscribe to. (https://feddit.uk/c/syncforlemmy@lemmy.world did let me subscribe.)

What’s the holdup? Do community owners get to decide whether I can subscribe? Is it something to do with the domains? Is it a local issue? I don’t understand what’s happening.
