Resolved Let's encrypt SSL certificates cannot be added / renewed to Forwarding Domains even though Nginx is installed and enabled on the server

Plesk version and microupdate number

18.0.45

On a new installation of Plesk 18.0.45 with Ubuntu 22.4LTS (with migrated sites from an old host) I have the problem that Let's encrypt SSL certificates cannot be added / renewed to Forwarding Domains even though Nginx is installed and enabled on the server. This problem did not occur on the old host.

Interestingly enough when switching the website temporary to regular website and disable Apache, so nginx is serving the pages and not acting as reverse proxy and then switching it back to Forwarding Domain, it works as it used to do and is expected.
