In my company the Internet proxy uses the Forcepoint technology. So every HTTPS connection is from my PC to the internal proxy interface, then the external proxy interface connects to the website using a new HTTPS connection. That means that for the internal connection the company's internal CA certificates are used while for the external the public certificates are used.
So if the web page loaded in my PC try to check the certificate, as CCW-R page does, it obtains the company's internal CA certificate and a Forcepoint error is showed, as this screenshot.

If the web page is interactive I push the "Visit Site anyway", instead if it is hidden the page remain stuck.
I hope that it is a common issue and that a solution exists.
Best regards,
