hi, i have a UTM PaloAlto whit SSL VPN Enable this Palo Alto use by default GlobalProtect Client i am trying to connect my Wyse 3040 and i get the next error:

XML response has no "auth" node

when i search for the error on internet i get the next solution: 

This VPN is based on HTTPS and ESP, with routing and configuration information distributed in XML format.
GlobalProtect mode is requested by adding --protocol=gp to the command line:
  openconnect --protocol=gp vpn.example.com

how i can add the parameter openconnect --protocol=gp to the Wyse 3040 ?
