Subscribing to this PieFed community says I've unsubscribed

Not sure if it is because it's hosted on PieFed, although that shouldn't matter, but trying to subscribe to !youdontmattergiveup@piefed.social gives a message saying I've unsubscribed. It also doesn't show any posts although there are some on the host instance (that's probably a federation issue though, nothing to do with Connect).
