S2s communication not working for multiple servers

Openfire Openfire Support

Hello,

our Openfire server does not connect to several other Jabber servers, for example “macjabber.de”, “jabber.ccc.de”, and “jabber.at”.

The error is always the same:

14:00:43 org.jivesoftware.openfire.server.ServerDialback - ServerDialback: OS - Ignoring unexpected answer in validation from: jabber.at id: 1355931159 for domain: mydomain.tld answer:<stream:features xmlns:stream=“http://etherx.jabber.org/streams”></stream:features>

I also tried to disable server dialbacks, but the error is still there. Does anyone know how to fix this or how to get the complete part after stream:error?
