Troubleshooting steps

You can also contact the ExpressVPN Support Team for immediate assistance.

  1. Change your VPN protocol
  2. Add ExpressVPN as an exception to your firewall, antivirus, or anti-spyware program
  3. Restart your device and reinstall ExpressVPN
  4. Contact the ExpressVPN Support Team

1. Change your VPN protocol

VPN protocols are the methods by which your device connects to a VPN server. For the best experience, ExpressVPN recommends using the Automatic protocol option. This is selected by default and automatically picks the protocol most appropriate for your network.

If you are unable to connect to ExpressVPN with the Automatic protocol, try the other protocols listed in the following order (if available):

  1. Lightway – UDP
  2. Lightway – TCP
  3. OpenVPN – UDP
  4. OpenVPN – TCP
  5. IKEv2

2. Add ExpressVPN as an exception to your antivirus or online security application

If you use the ExpressVPN app while an antivirus or online security application is running, your antivirus or online security application may block the VPN connection and give you a TLS handshake error.

To test whether your antivirus or online security application is blocking your VPN connection:

  1. Disable the antivirus or online security application on your device.
  2. On your ExpressVPN app, connect to a server location.

If you are able to connect to the VPN while your antivirus or online security application is disabled, your antivirus or online security program is blocking your VPN connection.

To resolve this, add ExpressVPN as an exception to your application. For other applications, you may need to:

  • Change the security level from High to Medium
  • Grant an exception to UDP ports 1194 to 1204
  • Set it to Trust ExpressVPN

Different antivirus or online security products have different steps for adding applications as exceptions. For specific instructions, contact your antivirus or online security application provider.

After adding ExpressVPN as an exception to your antivirus or online security application,

  1. Restart the ExpressVPN app.
  2. Connect to a server location:
