Yes, But why am I not able to hit CONNECTION_ESTABLISHED reason?I tried putting non-zero return value inside LWS_CALLBACK_FILTER_PROTOCOL_CONNECTION, but it just returns and waits for next events.

The only way to get that problem is return nonzero from the callback.

Check your callback's response to unknown reasons.... it should always return 0 like the test samples do.

That way if you don't deal with the callback, it does the default, sane action.
