So I'm starting to test your solution and immediately struck the following - can't properly start the host as it says can't bind port - the same issue is with all other ports (tried several random) Although those ports are not occupied in the system as per netstat -na report. No antivirus, internal firewall enabled, admin access, windows 10 pro x64 1803 (updated to latest)
23.10.2018---05:20:48:504 105 Unable to start TCP server. Check port: 5650 Could not bind socket. Address and port are already in use. 23.10.2018---05:20:48:516 34 Remote Utilities - Host 69014 is started.

Any suggestions? On the remote side i can see that host added to address book as live.
