Hostname not updating for PSA - Issue?

[raaqi]

I've changed the hostname in Server > Server Preferences > "Full Hostname"

The update has been successful somewhat, however when clients goto http://theirdomain.com:8443 they are redirected to the https://www.old-hostname.com:8443 instead of https://www.new-hostname.com:8443

Any ideas?

Found a temporary fix.

Edit:
/usr/local/psa/admin/conf/httpsd.conf


Replace:
ErrorDocument 400 https://old-host.com:8443
with
ErrorDocument 400 https://new-host.com:8443

Replace:
ServerName old-host.com
with
ServerName new-host.com

This may be lost next plesk update.
Why hasn't plesk updated the hostname correctly?
Is there a correct method for changing this?
Is it possible to have the domains redirecting to their own https://

Is this a Plesk VPS or Dedi?

What does 'hostname' output via SSH?

When you changed the hostname via Plesk, did you notice if the /etc/hosts file changed to the correct url?

Good Luck
