Hi Teege, sorry for the inconvenience.

The "Your connection is not secure" error page generally has an "Advanced" button to get more technical information. You can copy/paste that into a reply. The key data point is the error code, it usually starts with SEC_ERROR.

Does that help point toward the source of the problem?
