Using Mozilla Firefox, since today when try to login www2.pbxes.com getting error in browser "This Connection is Untrusted" and Technical detail shows
www3.pbxes.com uses an invalid security certificate.
The certificate is not trusted because the issuer certificate has expired.
(Error code: sec_error_expired_issuer_certificate)
Tried to add exception but failed as it was unable to obtain stauts for given site. (No information available)
My guess pbxes need to update the certificate.
