    Privacy Error


    I apologise now for what is by necessity, a lengthy post.

    I have a problem with accessing some websites when I get an error:


    “Your connection is not private
    Attackers might be trying to steal your information from Virgin Media - Official Site (for example, passwords, messages or credit cards). Learn more
    NET::ERR_CERT_COMMON_NAME_INVALID

    Virgin Media - Official Site normally uses encryption to protect your information. When Google Chrome tried to connect to Virgin Media - Official Site this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be Virgin Media - Official Site, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.
    You cannot visit Virgin Media - Official Site right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.”


    Virgin Media is just one site. Others include:
    bt.com
    bbc.co.uk
    itv.com
    channel5.com
    channel4.com
    news.sky.com
    national-lottery.co.uk
    amazon.co.uk
    amazon.de

    Bizarrely, I can access amazon.fr, amazon.it and amazon.es.

    I can also access skysports.com but not sky.com

    Observations:
    1. My PC has been working perfectly for several years. It is only since I changed ISP to Virgin Media that I have these problems.
    2. It only happens to my PC. Both my Android tablet and Android phone are OK.
    3. Everything is fine if I access via a VPN.


    Following advice received so far I have tried:
    1. Windows 10 is up to date
    2. The PC clock and date are fine
    3. Incognito mode gives the same results
    4. Using Edge gives same results
    5. Switching off Defender and firewall give same results
    6. I downloaded Brave browser. With some of the above sites it returns the same error message. On the others it returns a login page for SMART DNS Proxy.
    7. Run Malwarebytes and nothing found.



    This only started when I switched to Virgin Media so I have asked for help on the Community Forum, by phone and even had an engineer to the house. They say it’s nothing to do with them as my tablet and phone are working so it must be the PC. I maintain that my PC was fine until it was plugged into the Virgin Media service so they have to be part of the problem.

    I’ve totally run out of ideas now and would welcome any suggestion to resolve this situation please.

    Hi jetlagged, this sounds very much like a redirect bot or pup. I'd suggest you start with an online scan and then download and run Malwarebytes Free.

    Online Malware Detection | ESET

    Thanks. Malwarebytes has been run and did not find any problems. I've updated my original post.

    Thanks again.

    You're most welcome. Let us know the results of the Eset scan.

    Another thought, could you open an Administrative Command Prompt and type or copy & paste;

    Code:
    ipconfig /all
    + return and post the results in the thread.

    Be careful to redact or remove your 'Physical Address' mac info. Every connection will have a unique mac address, be sure to clear all of them.


    The fault you're describing could be the result of a faulty DNS entry and that is why a VPN connection produces a successful connection.

    Resetting network stack should work:

    System -> Network & Internet -> Network reset link

    Make sure to wait 5 minutes for reboot.

    I'll get back to you on the ESET if it ever finishes the scan!

    Try this:

    Virgin Media - Official Site

    (secure connection)

    Privacy Error-virgin-media.jpg

    Privacy Error-hsts.jpg

    Privacy Error-hsts-2.jpg

    Other than that reset router (hard reset button) and flush DNS then try another DNS. A reboot would be required.

    Does it work here?

    KPROXY - Free Anonymous Web Proxy - Anonymous Proxy

    For me https works but http fails.

    Thanks zebal. I'm still waiting for the ESET scan to complete before going any further. I'll have a go at this tomorrow and let you know,
