I have migrated my server to a new hardware. I created the users as before (same name, same email addresses, same passwords).
For XMPP, I made a copy of my rosters: /var/lib/metronome/domaine.org. I do have all my contacts and my chats rooms. The only problem is the connection between me and other users on my server. We cannot connect anymore.
I’ve created two new users and try to make connection between them without success. We can’t see the status of users but we can talk between the two users.
