My plain guess is that this is related a DNS hostname / FQDN mismatching. The broker code has to become more tolerant about this.We have tried running /usr/lib/x2go/x2gobroker-agent abo findbusyservers
and got this output:
OK
16:testterm2
83:testterm1
Which tells me that it might be the x2gobroker-daemon which isn't using the
information correctly.
