when your server is showing the country in the browser, you dont need to set anything on ServerAddress. if no country will shown (and ITC is installed), then add only the ip of your server, without port (eg: ServerAddress=18.104.22.168).
In the new version (1.0.4), XSQ will auto add the serveraddress, when the ip was found.
btw. i see, that you use version 102... you should update to 104
