1. Check your antivirus

If StrongVPN isn’t working on your PC, it’s possible that your antivirus is causing the problem. Sometimes your antivirus can interfere with the VPN causing this and many other problems to appear.

To fix the issue, be sure that your VPN is added to the list of exclusions. If StrongVPN is already on the exclusions list, perhaps you can fix the issue simply by disabling certain antivirus features.

If that doesn’t help, your next step would be to disable your antivirus altogether. This should fix the issue in most cases, but if the problem is still there, perhaps the best solution would be to uninstall your antivirus.

If you’re using Windows 10, you should know that Windows Defender will work as a default antivirus even if you choose to remove a third-party antivirus from your PC.

Once you remove the antivirus, check if the problem is still there. If removing the antivirus solves your problem, perhaps this would be a perfect time to consider switching to a different antivirus solution.

There are many great antivirus applications on the market, but if you want a reliable antivirus that won’t interfere with your VPN, you should definitely try out Bitdefender.

Another cause for problems with your VPN can be your firewall. As you probably know, your firewall can block outgoing and incoming connections from certain applications, including StrongVPN.

To fix this issue, it’s advised to temporarily disable your firewall. If you’re using a third-party firewall, be sure to disable it and check if that solves the problem.

However, Windows has its own firewall so you might have to disable it as well. To do that, follow the above steps.

Your firewall should now be disabled. Once you disable the firewall, check if the problem with StrongVPN is still there.

If StrongVPN works, the issue is related to your firewall, so be sure to check its settings and make sure that StrongVPN is allowed through it.

Bear in mind that disabling the Windows Firewall isn’t the best security practice, so be sure to turn it back on as soon as you can.


4. Use your phone as a hotspot

According to users, sometimes there might be an issue with your network connection that is preventing you from using StrongVPN. However, you might be able to fix this problem simply by using your phone as a hotspot.

Once you set your phone to work as a hotspot, connect to it and check if that solves the problem.

Bear in mind that this is just a workaround, but if this method works, it’s possible that your ISP is blocking StrongVPN, so be sure to contact it as well.


5. Be sure to try all VPN protocols

If StrongVPN isn’t working properly, it’s possible that the problem is related to VPN protocols. To fix this problem, users are suggesting to try all VPN protocols including L2TP, PPTP, and SSTP.

Bear in mind that this solution only works if you have a PPTP VPN account registered with StrongVPN.
