Hi Paolo,

In the log there is no evidence of the create_request request incoming from the client.
This means, unless you changed the log level for LightstreamerLogger.requests logger, that the client attempts to open the session towards a different endpoint than localhost:8080.

I confirm that you should check the client page code and in particular:

Code:
var client = new LightstreamerClient(null,"PROXY_HELLOWORLD");
Regards,
Giuseppe
