Can't subscribe to a lemmit.online community - eviltoast

Hey, I’ve been trying to subscribe to !audioproductiondeals@lemmit.online for a couple of days now and know the drill about searching it first and waiting for it to sync, but it doesn’t seem to be doing the job.

It looks like other lemmit.online communities seem to work fine, but this one seems to stubbornly refuse to show up.

Is there something I’m missing here?
