1. Preliminary checks

  1. Ensure you’re not connected to another VPN. Disconnect and close any other VPN programs you have before using your VPN.
  2. Check firewall and antivirus or anti-spyware program as these may be affecting your connection. You can test this by disabling these programs, then reconnect to your VPN. If disabling the programs resolves the issue, you’ll need to add your VPN as an exception before you enable them again.
  3. Connect to the server location nearest to your geographic location. If this fixes the connection issue, then the problem is with the server location you originally tried to connect to.
  4. If you cannot access even when disconnected from the VPN, check your internet connection.
  5. Check that you entered the correct user credentials – username and password for logins
  6. Check your IP address for information such as your city or region (country) next to the location you selected. If it shows a location near you, it means you’re not connected to a server location associated with your VPN, so try connecting again.

2. Change your VPN provider

4. Change your VPN protocol

change vpn protocol

Usually, the VPN connection works better when using TCP protocol instead of the UDP protocol. While your VPN is not connected to any server location, go to Options or Settings and find the Protocols tab or setting.

Most VPN clients will have this option set to Automatic. You can change this setting and select one of the protocols listed. Keep in mind that your results might vary depending on which protocol you’ve selected, so if you have more than two, we recommend trying all of them to see which works best.

Select the protocol you want to use and click OK, then restart your VPN and connect to a server location.

In some cases, you might want to reboot your PC as well after you’ve changed your VPN protocol.

5. Troubleshoot TLS handshake & network connection issues

  1. Restart your VPN client
  2. Update your VPN Client
  3. Change your VPN protocol
  4. Reboot your PC
  5. Pause your firewall/antivirus software

This problem occurs when the client and the server cannot establish a connection using the selected protocol.

6. Add an exception to your security program

Your firewall, antivirus, or anti-spyware program may block your VPN connection. You can test this by disabling these programs and then connecting to a server location on your VPN. If you can connect, configure your firewall, antivirus, or anti-spyware program to allow your VPN to connect.

Depending on the security program you’re using, you may need to change the security level from High to Medium, grant an exception to your VPN or to UDP ports, or set it to Trust your VPN, then restart your VPN.

Rarely, not using one of your VPN’s default DNS servers will provide a smoother connection. To do this:

  1. Open Network Connections settings by right-clicking Start and select Run
  2. Type ncpa.cpl and click OK
  3. In the Network connections window, find your usual connection, either LAN or Wireless network connection.
  4. Right-click the connection and select Properties

10. Switch to a different network

Try using a different network, such as a public Wi-Fi connection (or a mobile connection if your device has the capability), to see if the connection problem is with your current Internet service.
