VPN won't connect and no error message is displayed

I recently purchased a new laptop and installed Bitdefender VPN. When I connect to the VPN, it will show "Connecting" for a few seconds then goes back to "Turn On to Secure your Connection". What is the problem?

Hello @Juan Carlos Quinto and welcome to the Community!

There are a few general causes for connection errors encountered by Bitdefender VPN:

You are not connected to the Internet and can’t access the Internet via Wi-Fi or Ethernet cable. Make sure you have Internet access before using Bitdefender VPN.
A strictly configured firewall is preventing VPN connectivity (e.g. 3rd party firewall software, router’s built-in firewall). If you are not sure if your router comes with a dedicated firewall or how to turn it off please refer to its manual, contact the manufacturer or your ISP.
Another VPN or Proxy is running when you try to connect. In this case, disable the other VPN/Proxy solution.
You’re on a public Wi-Fi such as work, school, airport, etc. which may have blocked the ports required by Bitdefender VPN. You need to contact the network administrator to try and change their firewall settings.
The port used for the VPN connection is closed. Depending on the device you’re currently using, the port 443 UDP must be open.

Thank you for your answers. I opened the link to the Troubleshooting guide. I uninstalled the VPN and then reinstalled it. It now works.

Hi @Juan Carlos Quinto

I have the same problem. Reinstalling did NOT solve the problem. Logging out and back in did NOT solve the problem. No other firewall runnning. Running Windows 11 with all updates. Bought the product and it hasn't worked in months.

Hi @JRen and welcome to the Community!

Does the connectivity issue occur on multiple devices, or just a particular device? I'm asking because I have noticed that you have a Family Pack license that can cover up to15 devices, but the Premium VPN subscription will cover only 10 devices connected at a time, so we need to rule out this scenario first.

Referring to my previous comment, have you checked if the port 443 UDP is open?

I have the same problem. Reinstalling does not solve the issue. I am installing Bitdefender VPN in three different devices, and all of them has the problem. I contacted support team and they tried everything available solutions, but the issue still exists.

Hello,

Check if Port 443 is blocked. Port 443 UDP must be open for Bitdefender VPN to work. Also, 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. Try changing the DNS as well. Here's a video on how to do it:
