Device connection to remote server

[rafdelre]

We noticed that if the device is not connected to the wifi or internet connection and we try to do something in the app, it either crashes or keeps trying in a loop.

We need this to be Signaled to user.

It cannot crash if internet is not available

Also if the APP is left open for more than one hour, it doesn't work anymore.
Also "termina sessione con un consulente" locks without a timeout.
Exiting the app doesn't solve: when the app restarts, it shows the Y logo for 20-30 seconds, then it goes to scan but still not working.
App must be terminated.

Below is a dump of the TCP conversation.
The JSON-RPC client must simply handle the error, request a new token and redo the json-rpc request without any user intervention.
