Nope. Probably you have to search for the community you want, wait several seconds, then try again after it fetches that content. Lemmy's a bit idiosyncratic about that sometimes.
We are not defederated from them. The only 4 blocked instances are lemmygrad, lemmynsfw, and 2 loli instances.
Hm. I guess I'll have to go post there and try to figure out why it's broken, then!
Try searching specifically by the URL of a community, then when it comes up, hit subscribe.

It should eventually work. Maybe their site was overloaded or backlogged with federation when you tried it. I'm able to see some of the content there right now in the main feed though.
