Hi @Iqra_Mustafa1

Subprotocols should not be appended to the URI. You should add them with AddSubProtocol method to ClientWebSocketOptions which you can access through the Options property of your ClientWebSocket instance. Since subprotocols are negotiated during handshake, please make sure you add subprotocols before you connect.

Hope this helps,

Thanks for the help. It worked.
