@almagribi Hi, there is a "Set" configuration, I believe that we could generate the domain SSL somewhere else, then copy the cert and the key put to this place, and then I believe your URL will be shown with a valid SSL.
If you don't give it to your customers (I meant only you use it), I think you don't need to use a valid SSL for the URL.
if you want it for security purpose, there is the MFA with google authentication code, that's much better.
Thanks!
Dat.
