I downloaded the "streamingtools" zip file that contains the various websocket sample files and when trying out the Node.js samples, even though the app appears to successfully connect the websocket and login, after sending the initial ItemRequest there is no response from the server. No errors shown either... However, when trying out the Python samples, the server sends plenty of updates just fine. I thought maybe the sample files were bad, but when I downloaded the "Try it now" sample package, even the premade web pages had the same problem - websocket and login okay, but no updates or feedback from server.
