My servers have an "ugly" URL out of the box courtesy of my providers (both Strato and 1&1). It's something like h123456.stratoserver.net or s123456.online-homeserver.info. I've changed my host name to my own domain (let's say mydomain.com) and the IP resolves correctly. I can access the login screen via mydomain.com:8443 but the URL still changes to the "ugly" one I don't like. How can I change this permanently?
