How to setup non secure http2 for gRPC grpc/grpc-dotnet#505

https://learn.microsoft.com/en-us/aspnet/core/grpc/troubleshoot?view=aspnetcore-3.0#call-insecure-grpc-services-with-net-core-client-2

Using configuration file

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "Kestrel": {
    "EndPoints": {
      "EndpointDefaults": {
        "Url": "http://0.0.0.0:5220",
        "Protocols": "Http2"
      }
    },
    "AllowedHosts": "*"
  }
}

OR Using code

builder.WebHost.ConfigureKestrel(kServerOptions =>
{
    kServerOptions.Listen(IPAddress.Any, 8081, listenOptions =>
    {
        listenOptions.Protocols = HttpProtocols.Http2;
    });
});
