What community is it? Some ideas off the top of my head:
If the community is set to be local only when it is created, it will not federate
There was a short period where piefed.ca had issues sending activities after a recent upgrade (see this thread), so you might have just gotten unlucky. Make another post now that it is fixed and see if it is working now
Lemmy.world is having some federation problems at the moment so when I try to subscribe it stays on pending. But I expect that will resolve itself in the next couple of hours.

Ok, I’ll give it a shot creating some more posts. I didn’t want to start putting a lot of effort into the community if I just had to move it.
