If you click 'Add Exception' there should be a dialogue that details who the certificate issuer is, and other details about why there is an issue.

Do you have some AV/Anit-Malware software that is intercepting the requests with a cert?

No information on Cert. issuer..in the above dialog

No anti-malware software installed, it is a clean VM machine
