Issue domain uses plesk ssl certificate

Plesk version and microupdate number

Plesk Obsidian 18.0.73.3

Hello,

I have a problem with my ssl setup. I have two Lets encrypt SSL certificate, one for my domain and one for the plesk control page.
But when connecting to the pages on my domain I get an SSL error because it uses the certificate for plesk.
No matter what I try, my domain (and also Plesk) only uses the cert that is choosen via "Tools & Settings" > "SSL/TLS Certificates". Ignoring what I specified in "Websites & Domains" > SSL/TLS Certificate for mydomain.de.
I tried to use: plesk repair web -y via SSH, but I did not help.
Interestingly the mail and smtp servers work.

What am I doing wrong, here?

Hello, @biaaas . Are there any AAAA records in the DNS zone of the domain name? If yes, please try either removing them or assigning the same IPv6 address to Plesk.
