ssl certficate not included for port:2083
That will be resolved. Its due to a Lets Encrypt error. Anyway why?
Why are you accessing it over port 2083 when using just cpanel.epizy.com works fine? Plus the fact they don’t issue a cert for the domain on port 2083 so just use it without the port.
port 2083 does not work
The right URL to use is https://cpanel.epizy.com. So just the regular HTTPS port, not the cPanel port. Just don’t use that port.
