How to set Proxy in MessageWebSocket?

MangoApps 91

I want to set a proxy in MessageWebSocket..i got this "PasswordCredential ProxyCredential" but don't understand how to set proxy URL

Example proxy:

URL:- 127.0.01

Port:- 8888

Getting 403 error; Forbidden (403). (Exception from HRESULT: 0x80190193) When I remove manual proxy then it's able to connect successfully

Hi, have you tried to set the credential in your code?
Adding password and name like this: messagewebsocket.Control.ProxyCredential.UserName = test1;, messagewebsocket.Control.ProxyCredential.UserName = password1;

Now I am trying this with my local fiddler proxy that has UNTRUST Certificate
So I added that code
MessageWebSocket messageWebSocket = new MessageWebSocket();
messageWebSocket.Control.IgnorableServerCertificateErrors.Add(ChainValidationResult.Untrusted);
messageWebSocket.Control.IgnorableServerCertificateErrors.Add(ChainValidationResult.InvalidName);

still, it's Not working

It is currently unclear whether the problem is caused by the proxy settings or the way the UWP application handles the proxy. You can try to check Private Networks (Client & Server) in package.appxmanifest. If not work, you can try to create a WebSocket through another platform ( such as WPF ). If you cannot establish a WebSocket connection by other methods when the manual proxy is turned on, it may be a problem with the proxy settings.

UWP can't set proxy separately, it shares proxy with local. So the operation of the agent needs to be performed in the machine. In addition, I also need to confirm to you, in the package.appxmanifest have you checked the capability of Enterprise Authentication?
