"Can't connect securely to this page" / "This program cannot display the webpage"

Instead of the login window, you only see this warning:

Windows 10, 8 or 7 (with IE 11)

The text is:

Can't connect securely to this page

This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website's owner.

Your TLS security settings aren't set to the defaults, which could also be causing this error.

Windows 8 or 7 (with IE 10)

The text is:

This program cannot display the webpage

Most likely causes:

  • You are not connected to the Internet.
