Hope this helps - extracted from here

   INVALID_TUNNEL_PORT  

   Message Text in Browser:
   Tunneling is not allowed on this port. Contact your system    
   administrator.
  
   Explanation:
   The administrator has blocked the use of this port from requesting    
   secure requests from clients.

   Action:
   In the Appliance Manager, check both the Outbound Ports option (Setup  
   tab > Network > General) and the HTTP-Based Tunneling ACL option    
   (Setup tab > HTTP > Tunneling) to verify that the options are configured
   to block only the ports that you want blocked.

Good luck

I didn't mean to infer that you could reset the Appliance Manager from your pc, this is a function for your System Administrator.  

Good luck
