I have 4 domains on one server with control panel - Plesk All the domains and Plesk have the same shared ip.
The operating system my web server runs on is CentOS 7.8
Earlier Let’s encrypt certificates worked fine for for all of them, but recently installed Nginx as web proxy.
Unfortunately i have now a problem with the certificates - SSL_ERROR_BAD_CERT_DOMAIN.
https://www.ssllabs.com shows all of the certificates have Server hostname(rsvix170.gerwanserver.de) as domain name and not their own addresses.
