Try changing the protocol.

By default, ExpressVPN uses the UDP protocol, which is blocked in some countries, especially in the Middle East.

For optimal performance, please choose the protocols in the following order listed by priority:

  1. Auto (This automatically chooses the best protocol each time you connect. We recommend this option unless you specifically want to use a certain protocol)
  2. OpenVPN UDP

  3. OpenVPN TCP <-- Try this one

  4. L2TP

  5. PPTP

Note: We do not recommend using PPTP unless absolutely necessary. PPTP offers only minimal security.

To change the protocol for the ExpressVPN Mac App - version 3.X:

  1. Click Options.

  2. Under "Change protocol", select a different protocol, then click Back to locations list.

Try disabling your firewall, antivirus, or anti-spyware program.

Your VPN connection might be blocked by a firewall, antivirus, or anti-spyware program. To test this, disable these programs and see if can connect. If you can connect, please do one of the following:

  • If you know how to configure the program that's blocking the connection, configure it to allow ExpressVPN. Depending on the program, you may need to change the security level from High to Medium, grant an exception to ExpressVPN or to UDP ports 1194-1204, or set it to Trust ExpressVPN.

  • If you have the option to reinstall the program that's blocking your VPN connection, installing it after ExpressVPN is already installed should get it to allow ExpressVPN to connect. Do the following:

    1. Uninstall ExpressVPN.

    2. Uninstall the program that's blocking the VPN connection.

    3. Install ExpressVPN.

    4. Install the program that's blocking the VPN connection.
