Using a domain to reach HestiaCP

i have just started setting up and trying to figure out how to use this panel.
My current hostname under the basic setup tab is “sr1.lxvps.net”, which was defined during setup. Besides using the IP to load hestiaCP, do I use the above hostname to enter the panel? nothing seems to work. I have one domain setup that is pointed to another IP and has it’s own ns records, it’s working fine. How do I setup a domain to reach the control panel?
Also, is it possible to create a sub-domain?
thanks in advance.

I just run dig sr1.lxvps.net and the dns record was not found.

You will first need to add a dns record for sr1.lxvps.net. Then you can access the server on https://sr1.lxvps.net:8083

You may also tune your hosts file (your computer) to connect to the server
