Hello,
Thanks for joining the community and raising this issue!
First of all, not sure you would get more information about this error but there is a way to activate more verbose logs. Please have a look at the SonarLint for IntelliJ section of the FAQ.
I suspect it might be related to your certificate when I read
the common name does not equal the “sonarqube server” name
Normally the certificate should have the same name as the server.
Out of curiosity, what happens if you tick the box “Accept non-trusted certificates automatically” in the Server certificates settings ?
