Fixing common VPN errors and connectivity issues

Here you’ll find quick-fix solutions to common Bitdefender VPN connection errors on Windows, macOS, Android, iOS, or iPadOS. You will also find steps to take in the event the VPN is blocking an application, or if you can't access a website while VPN is active. Kindly note that some websites have implemented a system to detect VPNs and do not load or display errors if the Internet connection is filtered through a VPN. We cover this scenario as well. Regional restrictions may be involved and we have included a list of locations where VPN is banned.

    I went through the list to fix error code 12 but after removing the VPN I can't re-install it.

    "Bitdefender VPN encountered an error and is diabled. Please restart your device and try again."

    After restarting I still have the same error. powered down numerous times to no avail

  • Hello @crashdemo,

    I have noticed you are using the Premium VPN. What is the operating system on which you are attempting to install the VPN? Currently, you have two active devices assigned to the VPN.

  • I subscribed to Premium VPN. I updated it as required today but it has an error message "VPN - error code 12" and now I could no longer use it. I could not find or raise ticket for support anywhere except the long list of links which really could not help. I hope this is the right platform. In any case please assist or fix my problem. Thank you

    my VPN keeps disconnecting unticking the although I have the settings on my iphone 7

    also I cannot connect to some sites when VPN is on.

    can anyone advise me on these problems please,

  • uniformbeige1

    I should have read my previous comment before I sent it

    I meant to ask why does my VPN keep disconnecting although, I have ticked the automatic connect box.

  • Hello @uniformbeige1,

    In regards to websites that cannot be accessed with the VPN enabled, some websites have implemented a system to detect VPNs and do not load or display errors if the Internet connection is filtered through a VPN.

    Concerning the connectivity issue, there can be a couple of reasons why Bitdefender VPN fails to connect. Have you granted the necessary permissions to the Bitdefender VPN app? For a more in-depth analysis, I would recommend getting in touch with our Support Teams.

    ticket no: 1007417109

    if this is what PREMIUM is with your company, I am total disappointed. I have read several "fixes" to my problem, but I would prefer a simple link to click on and let the folks I am paying to fix it. I have sent emails and screen shots.... the big B hasn't sent me anything to help.

    If I have to take the laptop to a computer repair store... will the big B pay??


  • Hello @justkirk and welcome to the Community!

    I have taken note of your open inquiry and raised the priority of the case. It appears that the commercial teams could not find the root cause and the ticket was escalated to the technical engineers. Our colleagues will provide a response shortly.

    Premium VPN is not part of the Premium Services offered by Bitdefender, if you are referring to Premium remote assistance. Nevertheless, the response timeframe for submitted tickets varies between 24 to 48 hours, depending on the number of incoming requests and available resources. In the event a remote session is required to troubleshoot the issue, the engineers will carry out the operation without any additional costs, of course.

    Please do keep us updated on the resolution.

    Best regards

  • Hello, as off yesterday for some reason when i use telegram while my Bitdefender VPN is active telegram just seems to stop loading anything and seemingly refuses to connect. This was a rather recent development and its worked before in the past.

    For some reason its only on desktop as well and works perfectly fine on my phone even though i have the same VPN active on there. Any ideas on why or how to fix this?

  • Hello @Nitroz and welcome to the Community!

    I have noticed you've raised a ticket with our Technical Support Teams. The engineers have stated that Telegram might be blocking VPN usage in this case. Depending on their blocking mechanism, some VPN providers may still work, however, it is very likely that they will be blocked as well in the future. The Bitdefender VPN solution can be used to view geo-blocked content, but if the website/platform specifically blocks VPN usage, we cannot guarantee it will be accessible.

    As per our engineer's advice, it is best not to use a VPN connection with Telegram. In the event you are using a VPN connection quite often, you can apply split tunneling to bypass VPN while on Telegram. You can find out more on how to do this by accessing the link below:

    Scroll down to the Split tunneling section in the article.

    Split tunneling is available for Windows, Mac, Android, and iOS.


  • When trying to connect to VPN I don't get an error code. It just reverts back to the "Turn on to secure your connection" screen.

  • Hi @scotttow,

    I would check the internet connection first.

    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.

    Does it occur only on mobile data or wi-fi or both?


  • I love Bitdefender, but one thing that has been really annoying is the VPN app for PC. I am currently running the latest version of Win 11 on my computer at the moment. But I have tried this on other Win versions and once enabled. The VPN literally shuts down all access to any connection. Have no clue why but please fix this ASAP.

    Thank you!

    Hi @Landonez

    What other versions of Windows are you having this issue with?

    Kind regards,


    All Bitdefender Home Product User Guides:

  • Hello @Landonez

    Have you tried multiple servers as well? What app version do you have? Does the connectivity issue occur on WI-FI or data or both? We would require more information in order to advise accordingly.



  • @Tweedledee50 have you checked these possible causes? Have you also followed the steps from the articles above? What symptoms does the VPN show when trying to connect?


  • UPDATE: there has been indeed an outage and the situation was fixed by the development teams just recently, so if your VPN was in an endless connectivity loop, this has already been acknowledged and solved. Restart your device, open VPN and try to establish a connection now and let us know how it goes. Make sure to test multiple servers as well.


  • VPN keeps shutting off after a while, why?

  • Hello @McCoy,

    Just following up on this, can you tell us if the issue persists and what steps have you already applied in your attempts to correct this? My first recommendation would be a clean reinstall of the standalone VPN app, then check if your internet connection is stable, look for any errors displayed in the VPN app and also make sure the port 443 UDP is open. Try multiple networks and different servers too.

    Also, check if your router comes with a dedicated firewall and see how to turn it off. Make sure no firewall is preventing VPN connectivity (e.g. 3rd party firewall software, router’s built-in firewall). There can be multiple causes behind this behavior and more information might be required for accurate troubleshooting. If the connection still drops, I would advise contacting the Technical Support Teams for a more detailed investigation. You can get in touch with our engineers using the link below:

    Thank you

    VPNs are insecure because they expose entire networks to threats like malware, DDoS attacks, and spoofing attacks. Once an attacker has breached the network through a compromised device, the entire network can be brought down.

  • Hello @Adamjason,

    Reputable VPN networks usually employ the strongest and latest protection and fallback mechanisms to block any unwanted access that could compromise the security or privacy of any user while also ensuring top performance and quality of services. The privacy stance is enhanced by policies such as "zero logs" which acts as a failsafe, in the unlikely event that the network is breached, there would be no logs or data that could pose a risk for the user.


  • I was losing my mind with a VPN error code 2. After attempts to uninstall, reinstall and reboot my computer I found something I never imagined was the problem. I rebooted my internet modem. After the modem finished its reset the VPN connected immediately. I spent hours trying to diagnose the problem. How often does this happen and what causes it?
