11 Ways to Fix CyberGhost VPN Service Not Reachable

The CyberGhost VPN service is not reachable is the type of error that shows up all of a sudden, denying you access to its service for no apparent reason. Don’t worry, though.

This error isn’t nearly as bad as it sounds. I’ll explain all you need to get back to using the VPN fast. Here’s what you should know:

Why is CyberGhost not reachable?

If you get the Service not reachable error or CyberGhost VPN connectpage.error message when you attempt to access CyberGhost, there are multiple possible explanations:

• Servers are down – it’s possible that the specific VPN server you are trying to access is down or overpopulated, which makes it very difficult or impossible to connect
• Your Internet connection is bad – if your network is fluctuating or not working at all, your VPN will not perform either
• Security settings are blocking CyberGhost – your firewall or antivirus may prevent CyberGhost from accessing the Internet, thus connecting to a server
• These problems can be fixed if you check your configuration and change up your VPN setup. Read more below about what you can do.

How can I fix the CyberGhost VPN service not reachable?

Here’s a quick video summary that explains the error and proposes some fixes. I found it useful. But if you want further solutions and more details, keep reading this article.

1. Try a different server

1. In the CyberGhost app, click the little arrow next to your server location to open the server list.

2.  Go to All servers and pick another location. Double-click/tap on that location to connect to its server.

3. Wait for the connection to be established. If the main dashboard says “Connected”, congratulations! You fixed the error.

Switching a server is the simplest solution but could really save you because the service not reachable error might only occur on a server that’s temporarily down.

If you’re still having issues, try the steps below.

2. 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.

1. Open CyberGhost VPN‘s settings screen.
2. Head to the Connection category.
3. 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 the UDP setting.

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

3. Reinstall CyberGhost VPN

This method is quite simple, you only need to uninstall CyberGhost VPN from your PC and reinstall it from scratch. If you have problems such as the CyberGhost API not reachable domain fronting unsuccessful, a fresh install could help.

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, login 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.

4. 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.

5. 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/antivirus isn’t actively blocking CyberGhost VPN‘s access to the Internet.

Allow CyberGhost through the Windows Firewall

1. On your PC, open Settings and go to Update and Security.
2. Select Windows Security.
3. Click on Firewall and network protection.

4. Scroll down and pick the Allow an app through the firewall option.
5. Check the list of allowed apps. If CyberGhost isn’t there, select Add another app.
6. Browse for CyberGhost’s exe file and add it to the exception list.
7. Save your settings and try connecting to the VPN again.

Or, if you use a third-party antivirus:

Whitelist CyberGhost in your antivirus

1. Open your antivirus app find a Exclusion/Whitelist/Exceptions settings

2. Click the Manage Exceptions option to edit the list.

3. Identify the executable file of CyberGhost. Common executable names include CyberGhost.exe or similar. You can find this file in the installation directory of CyberGhost
4. Add the file to the list of exceptions and save your settings.

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.

6. Contact customer support

If the issue presists and you are not able to find exactly what’s causing it, you can try contacting customer support.

Luckily, CyberGhost has a 24/7 customer support service where you can contact an agent about your problem and they will look at your particular situation and find a solution for you.

7. Run CyberGhost in compatibility mode

1. Right-click the CyberGhost shortcut and select Properties.
2. Go to the Compatibility tab.
3. Check Run this program in compatibility mode for: and select Windows 8 or Windows 7.
4. Apply the changes and try running CyberGhost again.

On some Windows versions, CyberGhost may run into compatibility issues that prevent it from working correctly.

8. Disable IPv6

1. Open Control Panel > Network and Sharing Center.
2. Click Change adapter settings.
3. Right-click your active network connection and select Properties.
4. Uncheck Internet Protocol Version 6 (TCP/IPv6).
5. Click OK and restart your PC.
6. Launch CyberGhost and try connecting again.

IPv6 can cause routing issues with some VPNs, especially if your ISP or router does not fully support it.

9. Restart Cryptographic and DNS Services via Command Prompt

1. Click Start, type cmd, right-click Command Prompt, and choose Run as administrator.
2. Enter these commands one by one, pressing Enter after each:
   • net stop cryptsvc
   • net start cryptsvc
   • net stop Dhcp
   • net start Dhcp
   • net stop dnscache
   • net start dnscache
3. Restart your PC and check if CyberGhost connects.

10. Manually Switch to Google or Cloudflare DNS

This helps if your internet provider is blocking CyberGhost DNS lookups.

1. Press Windows + R, type ncpa.cpl, and press Enter.
2. Right-click your active internet connection > choose Properties.
3. Scroll and select Internet Protocol Version 4 (TCP/IPv4) > click Properties.
4. Select Use the following DNS server addresses and enter:
   For Google DNS:
   Preferred: 8.8.8.8
   Alternate: 8.8.4.4
   Or for Cloudflare DNS:
   Preferred: 1.1.1.1
   Alternate: 1.0.0.1
5. Click OK, then Close.
6. Reconnect to the internet and test CyberGhost.

11. Other suggestions

• Restart your PC, router, and/or modem
• Perform a clean install of your operating system
• Use an external network adapter
