Hi kan2332,

The IP address falls in the private IP address range 192.168. 0.0 to 192.168. 255.255.

Private internal addresses are not routed on the Internet and no traffic cannot be sent to them from the Internet, they only supposed to work within the local network.
 

This is probably the reason why you get the  "The underlying network was closed" error message.

Regards,

Daniel
