Diagnostics Your connection is not private

[Rory]

My broadband keeps dropping off and when the Now TV diagnostic page runs it errors as follows:-

Your connection is not private

Attackers might be trying to steal your information from broadbandconnection.nowtv.com (for example, passwords, messages, or credit cards).

NET::ERR_CERT_COMMON_NAME_INVALID

Reload

Help me understand

broadbandconnection.nowtv.com normally uses encryption to protect your information. When Opera tried to connect to broadbandconnection.nowtv.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be broadbandconnection.nowtv.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Opera stopped the connection before any data was exchanged.

You cannot visit broadbandconnection.nowtv.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

The error you show is a browser error, nothing to do with the broadband.

Try using a different browser.
