Cert error only on Tor Browser
Today I encountered an interesting issue where the cert of a website is valid both in chrome and firefox, but not in Tor Browser.
The site in question is: https://ykacademi.com/registration/
Tor Browser returns SEC_ERROR_UNKNOWN_ISSUER
but the issuer seems to be valid (Godaddy). After some digging, I thought maybe the reason is that the cert has been issued for a different domain (www.minervalms.com) but it has ykacademi.com listed in its DNS names. And even if this was the issue, Tor Browser is returning the wrong error. But I might be completely wrong about why this error accrues.
