My linux Openfire server 4.2.3 on LEAP 15.1 was working perfectly. I changed nothing that I know of. But now it rejects all connections. The server admin screen works. I have turned off the firewall.
I get messages like these:
2019.07.31 19:18:25 org.jivesoftware.openfire.net.SocketUtil - Unable to create a socket connection to XMPP domain ‘proxy.eu.jabber.org’: Unable to connect to any of its remote hosts.
2019.07.31 19:18:25 org.jivesoftware.openfire.session.LocalOutgoingServerSession[Authenticate local domain: ‘myserver.dyndns.org’ to remote domain: ‘proxy.eu.jabber.org’] - Unable to authenticate: Fail to create new session.
I do not have a proxy server
why is Openfire connecting there?
proxy.eu.jabber.org is unknown too.
ping proxy.eu.jabber.org
ping: proxy.eu.jabber.org: Name or service not known
nslookup proxy.eu.jabber.org
