I have a domain like this:
https://abc-.domain.com/. If I open this site different browser are showing me different results. E.g. Firefox throws the error security risk. Chrome on the other side loads the site without issues.
If I call the domain

The certificate should be valid for the following subdomains/domains:
I tried to verfiy the certificate with
openssl s_client -debug -connect abc-.domain.com:443 and can't find something wrong.
So is the hyphen not a valid wildcard character?
