Hi Ceelie, Unless you are on 5211R and have mail.ceelie.info <http://mail.ceelie.info/> added to your sites or web aliases and use a proper Let’s Encrypt cert, your server will report it is x10-server.fritz.box, which is not a valid hostname and will definitely not have a valid certificate.
Can you double check that? Google is very strict on these things nowadays.
