[PROBLEM]
If you get the following error message when trying to connect to a site over HTTPS:
Secure Connection Failed

An error occurred during a connection to sandbox.av-rd.com:10080. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
[SOLUTION]
Check if you're actually connecting to HTTP, but prefixed the URL with "https://".
Common example is, if you're port-forwarding or SSH-tunneling http+https connections to non-default ports, and accidentally mixed them up in the URL.

That's what happened to me 2 minutes ago.
A bit embarrassing, but happens :? :D
