remote control 8443 already in use

How can we change the port number used for remote control via Desktop Central? Tried restarting DC but didn't help.
We're on build v6.0.0 build 60227

Desktop Central uses TCP port 8443 for the remote control communication. This port is already used by some other service. Use edit settings to change the port number or free the port for Desktop Central to use.
