Since CyberGhost acts like a mask for your own network settings, and outdated network drivers can be the cause of VPN-related issues.

That being the case, we recommend you try a third-party software solution that will guarantee that all of your drivers will be updated, not just the network ones.

This tool is called DriverFIx, and it is lightweight, portable, and it has a library of all drivers that are currently in use, so it can detect any missing, damaged or old drivers on your PC and laptop.

2. Check your antivirus

 

According to users, sometimes your antivirus can cause this problem to appear. If CyberGhost is not working on your PC, try adding CyberGhost to the list of exceptions in your antivirus. If that doesn’t help, try disabling certain features or disable your antivirus altogether.

In the worst-case scenario, you might have to uninstall your antivirus. Several users reported issues with Malwarebytes and CyberGhost, so if you’re using Malwarebytes, be sure to uninstall it and check if that solves the problem.

Bear in mind that other antivirus tools can cause this problem, so you might have to remove them as well.

If removing your antivirus solves the problem, we suggest that you switch to a different antivirus solution. Bitdefender offers great protection, and it won’t interfere with your system in any way, so if you’re looking for a reliable antivirus, be sure to try Bitdefender.

3. Reinstall CyberGhost

If CyberGhost is not working, the problem might be the installation itself. Sometimes the installation can get corrupted, and in order to fix the problem, you need to reinstall CyberGhost. This is quite simple to do, but the best way to do it is to use uninstaller software.

In case you don’t know, uninstaller software is a special application that will remove all files and registry entries related to the selected application. As a result, you’ll remove all potential leftover files and prevent them from causing issues in the future.

If you’re looking for good uninstaller software, we suggest you try IObit Uninstaller. This uninstaller will also remove all leftover files thus performing a deep uninstall. Once you remove CyberGhost with uninstaller software, download and install the latest version and check if that solves your problem.

According to users, sometimes CyberGhost is not working due to problems with your network connection. This is a relatively common problem, and in order to fix it, you need to run several commands in the Command Prompt.

After running these commands, check if the problem with CyberGhost is still there.


6. Make sure that your network connection is working

If CyberGhost VPN isn’t working on your PC, perhaps the problem is related to your network connection. To fix the problem, be sure to check if other applications, such as your browser, for example, are working properly.

If the network connection works, you can proceed to the next solution.

Sometimes your system time can cause problems with Cyberghost, especially if your clock isn’t correct. To fix this problem, be sure to check your clock.

After doing that, the date and time should be readjusted automatically. If you want to change date and time manually, click the Change button and adjust it.

After your date and time are correct, check if the problem is still there.


8. Make sure that the required ports are open

  • 443
  • 8078

In addition to the firewall on your PC, perhaps you should check your router’s configuration page and make sure that the aforementioned posts are open there as well.

  2. When the Settings app opens, navigate to the Update & Security section.
    check for updates cyberghost not working
  3. Now click Check for updates button in the right pane.

If you keep having issues with CyberGhost, perhaps the problem is caused by system glitches. Problems on your operating system can occur and interfere with various applications. However, you should be able to fix most of these system glitches simply by updating your system.

Windows 10 already installs the missing updates automatically, but you can always check for updates manually.

If any updates are available, they will be downloaded automatically and installed as soon as you restart your PC. Once the latest updates are installed, check If the problem is still there.


10. Run CyberGhost as an administrator or in Compatibility mode

If CyberGhost is not working on your PC, the issue might be the lack of administrative privileges. To fix this issue, users are suggesting running CyberGhost as an administrator. This is actually quite simple to do, and you can do it by following these steps:

  1. Right-click the CyberGhost shortcut.
  2. From the context menu choose Run as administrator.

If this works, CyberGhost should now start without any problems. Bear in mind that you need to repeat this step every time you want to start CyberGhost. However, you can automate this process and set CyberGhost to always start with administrative privileges.

To do that, follow these steps:

  1. Right-click CyberGhost shortcut and choose Properties from the menu.
  2. Navigate to the Compatibility tab and check Run this program as an administrator option. Now click Apply and OK to save changes.
    run as administrator cyberghost not working

  1. Right-click CyberGhost shortcut and choose Properties from the menu.
  2. Head over to the Compatibility tab and check Run this program in compatibility mode for and select the desired version of Windows. Now click Apply and OK.
