Resolved Plesk custom url does not work

Hi,

The Plesk custom URL setting doesn't work. When I try to change this to any of the settings, I can still access the control panel from any domain on port 8443. This needs to be fixed as it's failing a cyber scan for the domains hosted on the server. The control panel needs to be closed for all other domains except the domain the certificate is configured for.

That's correct behavior. Using a custom URL does not disable access on port 8443. If you want to block access on port 8443 you'll have to create a custom firewall rule to do this.

Hi, I don't want to block access to port 8443 for the correct encrypted subdomain. I just want to block all the hosted domains from having access to the control panel on 8443. Is this possible with a firewall rule? If so how?

There is no feature in Plesk to do this. However this support article suggests two possible workarounds which you can try:
