Server Settings > Change Hostname... You can see a list of all the links to use.
Thanks that was helpful. BUT how do i allow user to login from their domain
e.g. userdomain.com:2083
When I login from my.serverhostname.com:2083 it works fine but not for userdomain.com:2083.
I have secured userdomain.com with Let's encrypt and verified the SSL using
www.sslshopper.com/ssl-checker.htm and I get green padlock on all counts for the userdomain...... but no joy for login screen - only get the "this page is not secure" message.
I've cleared cache and even tried with different browser and different machine - but always the "this page is not secure" message.
So - how can I allow user to login from their domain userdomain.com:2083
