I think there is a misunderstanding.
TLCP-2.0.0.lightstreamer.comis the WebSocket subprotocol (for the sake of precision, it's called the
Sec-WebSocket-Protocol ), it's not the address to connect to.
medvedtrader As an aside - maybe this should be clarified in the doc instead of giving that TLCP-2.0.0.lightstreamer.com address to connect to.
