When trying to access one of our firewalls on the web console using a MAC we got the above error.
We have removed the certificate and Sophos Endpoint protection which did solve the issue. We then reinstalled SEP without any issues, however the above error has now returned. even proceeding to the unsecure page of the web console gave us the same error. please see below for full error details.
