CyberGhost VPN service not reachable

CyberGhost VPN service not reachable is the type of error that we use to call a showstopper.

There’s no warning, either. One day you wake up and CyberGhost VPN just stands there, denying you access to its service.

For many people, lacking a VPN might be no biggie, but users who are concerned about their online privacy and security are really affected by this issue.

However, you shouldn’t worry. This error isn’t nearly as bad as it sounds.

In fact, many users report that a simple restart did the trick for them, so maybe you’re among the lucky ones.

Either way, we’ll walk you through the most common ways you can fix the CyberGhost VPN service not reachable error in no time.

How can I fix CyberGhost VPN service not reachable?

Try a different server

Sometimes CyberGhost VPN‘s servers can get overcrowded.

As a result, you may experience connectivity issues such as the service becoming unavailable.

If that’s the case, you’re among the lucky ones.

Simply choosing another VPN server and connecting to it should get you up and going in no time.

If that doesn’t work, log out of your account in the VPN client, close the CyberGhost VPN app, re-launch it, and log back in.

Now try connecting to another server and everything should work just fine.

Switch protocols

It’s not exactly classified information that certain protocols could sometimes work better than others.

If your CyberGhost VPN client is set to choose its own protocol automatically, try changing this setting.

Open CyberGhost VPN‘s settings screen, then head to the Connection category.

Select a different option from the VPN protocol dropdown menu and check if there’s any improvement.

If you still get the CyberGhost VPN service not reachable error, try toggling the Use TCP instead of UDP setting.

Still nothing? Disable the Use a random port to connect option.

We’re quite confident that if this issue was caused by a stubborn protocol/port combination, this should’ve done the trick.

Reinstall CyberGhost VPN

This method is quite simple, you only need to uninstall CyberGhost VPN from your PC and reinstall it from scratch.

However, you also need to make sure that CyberGhost VPN‘s TAP adapter driver is also uninstalled during the process.

  1. Right-click your Start Menu
  2. Select Device Manager
  3. Expand the Network adapters category
  4. Right-click the TAP adapter driver (provided you only have one VPN installed on your PC)
  5. Select Uninstall device
  6. Restart your PC

Once your PC comes back to life, go ahead and download the latest version of CyberGhost VPN. Now install it.

When the setup process comes to an end, log in to your account, and check if the problem is gone.

Also, you should try to launch CyberGhost VPN as an Administrator. You know, for good measure.

Flush your DNS

  1. Launch CMD with Administrator rights
  2. Type these commands one by one, and press Enter after each of them:
    • ipconfig /flushdns
    • ipconfig /registerdns
    • ipconfig /release
    • ipconfig /renew
    • netsh winsock reset
  3. Restart your PC

After your PC finishes its boot sequence, launch CyberGhost VPN and check if it’s still unavailable.

Sometimes cached data can mess with your connectivity, and your VPN makes no exception from this cruel situation.

Simply flushing your DNS and resetting your Winsock should take care of things in a jiffy.

Check your firewall/antivirus

If you recently installed CyberGhost VPN and remember skipping some permission-related dialogs from your security software, keep on reading.

Usually, your Windows Firewall detects whenever you’re about to run an Internet-enabled program for the first time and asks you what to do.

Depending on your security settings, skipping the dialog by closing the window or clicking the Cancel button could mean extra restrictions.

For that reason, you’ll need to check that your firewall isn’t actively blocking CyberGhost VPN‘s access to the Internet.

Once you make sure that your firewall isn’t restricting CyberGhost VPN, you should do the same thing with your antivirus. You know, for good measure.

Use another VPN

Private Internet Access
  1. Purchase a new VPN subscription plan (we recommend Private Internet Access)
  2. Download the VPN installer
  3. Install the new VPN client on your PC
  4. Launch the VPN client and log in to your account
  5. Choose a server and connect to it

If nothing seems to cut it, maybe it’s time to part ways with your current VPN and turn to another such service.

Private Internet Access, for instance, is another great product from Kape Technologies that provides you with great security/privacy features.

Furthermore, it has over 22,000 servers (and counting) you can easily switch between in case your current one doesn’t work.
