Typing that into search engine produces a thread explaining that it is the browser message shown when HSTS is in effect on a website and the server cert is not trusted by the browser. > 3.

Well, first step is to ensure your ca-certificates package is up to date. That usually solves these. But not always, especially if the CA has been caught doing bad things and suddenly dropped. Or if they have begun issuing certs to clients before being accepted by the Mozilla CA list people. It could also be a problem with intermediary cert just being omitted by the server. In that case adding it to your server-wide cert store or configuring it to be loaded by Squid will be needed.
