  • @BD Seems like a whole lot of stuff to do, in order for your product to work right.

    I wonder if I can still get my money back so I can go with someone else?


  • Hello @knott,

    That's a bit generic, don't you think? 🙂

    Can you share with us exactly what seems to be the problem/error message you are experiencing?

    Due to a large number of possible system configurations and installed software, determining what might cause an issue with a specific Bitdefender module/feature is not as simple as it sounds and everything must be taken into consideration. For this reason, a debug log from the affected PC is sometimes required, in the event the basic troubleshooting steps don't fix the issue you have encountered. The support teams created a special tool to diagnose and troubleshoot Bitdefender installation failures or product issues on Windows computers. This Support tool collects details required for debugging technical issues, such as logs and product usage information, thus in some cases this means the user is required to follow a couple of steps to generate the logs and send them to the Bitdefender engineers for further investigation.

    It's like when your engine management light comes on and you take your car to the mechanic. They will have to investigate thoroughly to find the source of the problem, they won't know what's wrong just by looking at it from a distance or listening to the engine over the phone.

    Of course, if you are not satisfied with your Bitdefender purchase, you can request a refund within 30 days of your initial purchase or of the automatic renewal date by using the link below:

  • No. I don't think it's generic to say. And the difference in the check engine light coming on, in my $45,000 car and my $50 vpn not connecting is really quite different. A check engine light coming on, doesn't make the car turn off!

    But keep on thinking it's relatable, Genius.

    No worries though. I got your vpn to work with a computer reboot.

    But since I've had the program over 30 day's, I'll wait till the service is up and use one of the many vpn's out there.

    I was using CyberGhost. But that was for a vpn only and I needed an AV as well.

    At any rate. I'll figure it out.

    Thank's Jeff

  • Hi @knott,

    Through the earlier comparison, I was trying to highlight the fact that there can be several reasons why the vpn may not connect. While connectivity issues may also be caused by a specific server that you are connecting to, if we remove the infrastructure from the equation, or a possible bug, there are a few common causes of Bitdefender VPN errors, as the support article on this topic explains:

    • No Internet – Make sure your device is connected to the Internet with a fast and stable connection.
    • Firewall – Check that your firewall isn’t blocking the VPN. If you’re not sure, look in your router’s manual, contact the manufacturer or your Internet provider.
    • Another VPN or Proxy – If you’re running another VPN or Proxy, disable it when trying to connect.
    • Public Wi-Fi (like in a hotel, school, or office) – Contact the network administrator to see if they can change the firewall settings and allow the VPN connection.
    • Port 443 is blocked – Port 443 UDP must be open for Bitdefender VPN to work. Access your router’s settings by typing its IP address into a web browser (refer to your router’s manual if necessary), find “Port Forwarding” or a similar section, and ensure Port 443 with UDP protocol is allowed. Save settings, then restart router and computer.

    True, you may still drive with your check engine light on, but in many cases it's a matter of time until it goes into limp mode. 😉

    If the issue is not caused by the VPN itself and the problem is elsewhere, the situation can persist with another vpn as well. This is why I recommend going through the basic troubleshooting steps before anything else.

    Of course, it's entirely your decision to make. I was just trying to help, you can take it as it is or as you see fit.
