The Web Socket URL on a Stream Service on an Amazon EC2 machine always assumes the internal IP address of the machine. Clients accessing the Stream service from outside of the EC2 machine are unable to start or subscribe to the Stream Service.

Additional Information

The workaround in this case is the correct way to do this, by providing the WebSocketContextURL value.


External clients cannot resolve the internal (private) IP address of the server. They have to reach the server through a public IP … for example.So you would need to specify, to ArcGIS Server, that the correct Web Socket Context URL to use is:{"WebSocketContextURL": "ws://"}You do not need to restart ArcGIS for Server to affect a change in the Web Socket Context URL. If you walk through steps 1, 2, and 3 above – you should see the change reflected in the stream service REST specification page if you refresh the page.
