    Can you provide more details like the URL and have you tried two browsers? Is it the main www.red-gate.com site? documentation.red-gate.com? You posted here, is it an issue from another location or computer?

    I have had this issue with some MS sites if I'm using Firefox, but Edge and Chrome will work.

    Hi,
    It looks like your certs are ok. I believe it is failing during the “upgrade-insecure-requests” handshake.
    I don't get a cert error, I get a protocol error.
    It happens on many sites for RedGate (and also other orgs).

    I believe it has to do with the security protocols supported by your server. They do not seem to be compatible with what my organization is requiring.

    ERR_SSL_PROTOCOL_ERROR

    Is there something your organization requires for protocols that you can share?

    I'm not an expert in this area, but here are some findings.
    Test The Server:
    https://www.ssllabs.com/ssltest/index.html
    Test the Client:
    https://www.howsmyssl.com/

    I think this is an issue for the IT department for Web Server security configurations.
