subscription issue from other instances - Lemmy.world

I cannot subscribe to some communities on external lemmy instances (not lemmy.world). On the page with subscription list [https://lemmy.world/communities?listingType=Subscribed&page=1] most of lemmy.ml [http://lemmy.ml] communities are “subscribe pending” (but a few are subscribed correctly). Also one community from lemmy.one is pending. Should I try to resubscribe to them? Or just give them some time?
