connection fail Flukso

Good morning,

I have tried to install my Flukso but had contrasting results.
The configuration went smoothly until the point at which, once on the dash page, I was notified after some minutes of functioning of a connection problem between the Flukso and the computer, whether the connection was done through a wifi or ethernet connection and with the LAN cable between computer and Flukso always connected. Could you please give me a hand with this??

I have attached a picture of the error message.
Here it is in case the upload didn't work:
'The call for sensor PV experienced a timeout. You are probably not in the same local network as the FLM'.

Thanks, Stefano
