My UWP MessageWebSocket not working behind the proxy when i set proxy manually its through 403 error; Forbidden (403). (Exception from HRESULT: 0x80190193)
When I remove manual proxy then it's able to connect successfully
NEED TO USE ANY OTHER CLASS FOR SOCKET CONNECTION BEHIND PROXY LIKR "StreamSocket" etc
HTTPS calls working well only issue with MessageWebSocket
its there anything need to do in code to connect socket connection behind a proxy server?

MessageWebSocket. In your other question, I see that you seem to have noticed this. And you can check the request header changes when the proxy is not set and after the proxy is set to analyze the possible cause of the problem. -

2020-04-15T04:53:22.283+00:00 No, my server doesn't have any credentials
and if there are any errors in certificate or credential how my "Https" call working and only problem with TCP/Socket
and we are not setting any request header from client its just
URL:- wss://hubnew2.example.com:5223
Port:- 5223
await messageWebSocket.ConnectAsync(new Uri(URL)); -

2020-04-15T05:21:30.29+00:00 Hi, I can't reproduce your problem for the time being, you can try to listen to the
MessageWebSocket.ServerCustomValidationRequestedevent, which applies to wss, here is the relevant documentation. You can check whether the event is triggered. -
