Running App on TV with LG IDE

Question

I have a LG SMART TV Upgrader LG SP820.

I'm following this instruction trying to run Running an App on TV with LG IDE:

http://developer.lge.com/resource/tv/RetrieveDocDevLibrary.dev

From the TV Browser I get a message:

Cannot connect to destination IP address

I have also installed WAMPSERVER and with WAMPSERVER I'm able to run successfully the page on localhost.

What could prevent LG SMART TV to connected to my local computer?

Answer 1

The problem was TV and PC were not on the same Switch (even if in the same network).

Connected TV and PC on the same switch solved the problem
