VPN CONNECTION PROBLEMS

Hello @Catgalkid,

What are the symptoms for the connectivity issues you are encountering? Are there any errors displayed in the VPN UI? is the VPN stuck at connecting or reconnecting?

There are a few common causes of Bitdefender VPN errors:

• 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.

Bitdefender VPN allows you to switch protocols. By default, Bitdefender VPN is configured to automatically select the optimal protocol for your device and network – usually a balance of speed and security. Try changing the protocol in Bitdefender VPN’s settings until you identify one that works for you.

If you’ve already checked the above reasons, I would recommend contacting the Technical Support Teams, as more information might be required to troubleshoot this. The following details may help the Bitdefender engineers troubleshoot the situation you are encountering:

• The OS and version on which the VPN is running.
• For traffic/subscription issues, they need to know the affected account.
• For functionality issues while the VPN is connected, whether the problem occurs on a specific location or all locations
• IP of the affected server(s)
• For split tunneling issues - the applications/sites affected
• Whether the problem occurs only on mobile data/Ethernet or only on wifi or present on both. Preferably try multiple networks
• App version

Let us know how it goes.

Hi @Phystar,

What exactly doesn't work and when? What are the symptoms? Like I wrote earlier, we need more information to be able to advise in such scenarios.
Once updated, the VPN version cannot be reverted.

Alex

Can you switch protocol to Wireguard please, and let me know if it makes any difference?

You can also test the other ones, but Wireguard would be my first pick.

Alex,

What's next? I would prefer the previous version until Bitdefender can figure this out, please. Thanks in advance.

Hi Alex,

Thanks for the above post with this excerpt.

My results were as follows…..
Automatic - No connection error 1(Hydrakilled)Hydra
Catapult - No connection error 1(Hydrakilled) or error code9
OpenVPN UDP - Connects
OpenVPN TCP - Connects
Wireguard - Connects

Question? Do you have port forwarding enabled on your router? If so, then any of the above protocols would work.

My ISP warned me not to enable port forwarding on my home wireless network as doing so would make my network vulnerable to cyber-attack, and I agreed. I am not accepting that risk because Bitdefender screwed up. I may have to cancel my subscription and go with a competitor product.

Thanks again for your time and assistance.
