Python PnP server workings

Need  to upload a configuration with the  upgrade-config task on a switch in a local network by using the pnpserver.py script.

It's not showing any errors but it doesn't seem to work either.

Have placed and compiled the pnpserver.py on a windows 2008 server, changed the policy file just for the upgrade-config part, created a self-signed certificate for HTTPs testing in OpenSSL. Regarding the signal handler request (SIGUSR1 and SIGUSR2) , Have terminated it by putting the SIGTERM instead.

        signal.signal(signal.SIGTERM, sig_handler_usr1)

       signal.signal(signal.SIGTERM, sig_handler_usr2)

signal handlers are a UNIX "thing" so I didn't know what to do else.

Is there any documentation for the pnpserver.py. 

The executing command is

python pnp_server.py --http --port 9443 -f service-template.xml  --preconfig policy -i 10.x.x.x where 10.x.x.x is the IP address of the web server where the script is executed

The switch is IE 3000 -8TC, IOS: 15.2(5)E
