If I have a certificate which is issued to *.abc.dk, I can get to the site with for example vm.abc.dk fine (changes automatically to https://www.vm.abc.dk) but when I try to write www.vm.abc.dk I get the error SSL_ERROR_BAD_CERT_DOMAIN in Firefox and similar error in Chrome.
If I choose to proceed or add an exception, it is able to redirect to https://vm.abc.dk fine. Do I need to add a SAN to my certificate, or what is the reason that I can't connect instantly with www.vm.abc.dk?
