Yesterday we took over the domain openim.de and the XMPP/Jabber users running on it. The service would have been discontinued at the end of the month and as we think that a takeover is much more in the interest of users, we agreed to the old operator’s proposal. The import of the user accounts and user data took many hours, but everything should be running again by this morning at the latest.
We noticed that there are currently many requests with invalid encryption on port 5223. With us, port 5223 (in contrast to the old openim.de server) is only used for Direct TLS (f.k.a. SSL) and not STARTTLS. Please adjust the connection settings in the clients accordingly! Information about our server can be found here.
Further questions? Gladly in the MUC support channel or here under the post as a comment.
