AP Connection "out of sync" after deleting and re-establishing connection
I have a hubzilla and a pleroma single user instance and an account on a friendica and a mastodon instance.
My Hubzilla instance seems to have a problem with all of them. Everything was fine, I was able to connect with all of them and connected back from all of them.
Then one day my hubzilla account was displayed as ID.accountname@domain ("ID." was new) on my pleroma instance.
So I deleted this connection and tried to connect again. This seems to fail: The connection from Pleroma stays in state "waiting for answer" forever and Hubzilla displays no connection request from Pleroma (what is correct, as I have enabled auto accept). But Hubzilla does not display an incoming connection either.
On the other hand Huzilla is telling me it is following the pleroma account but it is not displayed as a follower there.
Deleting both sides and doing it again produces the same.
A similar problem occur when I delete the other connections on both sides and re-establish:
* Friendica shows connection both sides, Hubzilla only from its side
* Mastodon shows connection both sides, Hubzilla only from its side
There seems to get something "out of sync" when I delete connections with AP accounts. Is there something known as a bug? Or an idea how to clean this?
