    Set the GlobalProtect connection timeout to 60 seconds on the Palo Alto server

    Increase the authentication timeout to 60 seconds.

    As the LastPass Authenticator app push notification timeout is 60 seconds, set to 60 seconds.

    The authentication timeout is calculated as: set connection timeout - 5 seconds. The default timeout is 30 seconds, which in turn makes the default authentication timeout as 25 seconds.

    You can only change the authentication timeout settings from CLI:

    1. SSH into the Palo Alto server from the command line.
    2. Run the following command to increase the default timeout value to 60 seconds:
      vpnadmin@paloaltovpntest> configure
      Entering configuration mode
      vpnadmin@paloaltovpntest# set deviceconfig setting global-protect timeout 65
      vpnadmin@paloaltovpntest# commit
      Note: In order to set the timeout to 60 seconds, you should add timeout 65, 5 seconds more, because of the server's calculation.
    3. Run the following command, to check the previously modified settings:
      vpnadmin@paloaltovpntest#  show deviceconfig setting global-protect


      If set correctly, the following result appears:

      global-protect {
        timeout 65;
