Hello,

I've used x2go on a very similar setup in the past but I'm running into a problem on a new installation.  I've installed x2goserver on a CentOS 7.5 machine - simply a yum install via EPEL.  I'm trying to connect from a Mac running 10.13.  I can ssh password free between the machines with no issues.  When I try to connect with x2go, I get this in my client window:

Error: Failed to resolve address of 'localhost'.
Loop: PANIC! Unknown remote host 'localhost'.
Error: Unknown remote host 'localhost'.
Session: Session terminated at 'Tue Nov 27 08:06:01 2018'.

On the server side, I see this in /var/og/messages:

Nov 27 08:06:01 valkyrie /usr/bin/x2gostartagent: successfully started X2Go Agent session with ID dvicker-51-1543331158_stDMATE_dp32

The server machine is in our local DNS and I've made sure the IP address is in /etc/hosts and matches the hostname.  Any idea what is going on here?  Is there a way to disable the host lookup?
