Impossible to add custom domain to installation

[nadertech22]

I'm unable to add custom domain to installation, the mail server domain feature works fine, but installation url is only accessible via IP with /access_point --> example: IP:/kcslz98

When creating A record in Cloudflare and pointing it to server IP, and try to access site via domain i get "Not found" blank page.

Why such complication for a simple feature? Please allow custom domain insertion on settings page, otherwise this is useless and not safe to use if we have to expose server IP for access.

You must visit your_domain:port/kcslz98 again and you can access other pages. This is created by security.
