I have a OpenBSD server 5.6, in this server install Openfire 3.9.3.
But I am getting the following error:
2015.02.16 08:59:44 org.jivesoftware.openfire.session.LocalOutgoingServerSession - Error creating secured outgoing session to remote server: riseup.net(DNS lookup: xmpp.riseup.net:5269): java.lang.RuntimeException: Could not generate DH keypair
it is repeated several times, and I have no more errors or info in the logs, I have self-signed certificates.
in the buddy list contacts this server appear as a 404 server not found.
I hope for your help no where else resort
