Installation failed

I follwed the setup guide for server and everything looks good to me.
But at the end i get this message

Installation failed.
Can't start ejabberd.

When trying to install with QUICK mode, it says that the srv- records does not exist. But when i
lookup

_xmpp-server._tcp.xabber.xmpp2.renawo.at

and

_xmpp-client._tcp.xabber.xmpp2.renawo.at

there is nothing wrong with it.
