Download the Website CertWhen you are at the webpage, and you get the error
Go to the top of the browser, and inspect the certificate.
Then (on a mac), click on the icon of the certificate (3), and drag it (4) to the desktop. This will save that websites cert for you to authenticate later.

The certificate will show up in the keychain, and then select it. Then in the cert window, select each of the settings and "trust" them. Re login with your browser
