            }
        }

The issue appears when grpc server returns data to the client.

Environment details OS: Windows 10 Package name and version: .NET Core v3.1.7 & Grpc.Core 2.31.0 & protobuf-net 3.13.0

I have the same problem in UWP aplication, here my code:

AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

var handler = new HttpClientHandler();
handler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;

var channel = GrpcChannel.ForAddress("https://localhost:5001", new GrpcChannelOptions
                    {
                        HttpHandler = handler,
                        Credentials = Grpc.Core.ChannelCredentials.SecureSsl
                    });

var client = new Greeter.GreeterClient(channel);

var replay = await client.SayHelloAsync(
                 new HelloRequest
                  {
                      Name = "Jose Antonio"
                  };

After this always the same error: Status(StatusCode=“Cancelled”, Detail="No grpc-status found on response.

How can i solve this problem
