julian Those are not Lemmy communities but authors of a federated Wordpress blog: the author skariko is followed while the authors marcocalamari and fediverso remain in “pending”.
On the other hand as far as PeerTube is concerned I just tried it and it did not give me any errors, in the next few days I will try to see if new posts also appear to me but it seems so: https://citiverse.it/category/framablog.audio@framatube.org
Thank you 
Hello
I am trying to follow some different ActivityPub group and users but
but I can't quite understand why some are accepted while others remain "pending."
For example, here I was able to follow the profile skariko@www.lealternative.net (who is an author of a Wordpress blog) and in fact his posts are posted in autonomous in the category correctly.
But if I try to follow another author of that blog like marcocalamari@www.lealternative.net or fediverso@www.lealternative.net it remains in “pending”.
I have also tried following two PeerTube users who both remain in “pending.”
Also after trying to unfollow one of the users it remains in “null.”
