I am starting a gRPC server on my local machine using the machine's name as the host name:
new ServerPort("MyMachine", 9017, ServerCredentials.Insecure),
I am running this server code via Visual Studio. I can then connect to that gRPC endpoint just fine by running a client app, also from VS:
var channel = new Channel("MyMachine: 9017", ChannelCredentials.Insecure);
I can successfully call a simple "ping" API. I can also telnet MyMachine 9017 without error.
However, when I then try and connect from another app (LINQPad), I get an error:
RpcException: Status(StatusCode=Unavailable, Detail="Name resolution failure")
The gRPC trace for "channel,api,handshaker,op_failure" is as follows:

I'd try other tracers, such as client_channel, client_channel_routing, cares_resolver etc. The "No error" message is an internal thing and has nothing to do with whether the call as a whole has succeeded. You should also specify which platform and grpc version you're using.

I'd try other tracers, such as client_channel, client_channel_routing, cares_resolver etc. The "No error" message is an internal thing and has nothing to do with whether the call as a whole has succeeded. You should also specify which platform and grpc version you're using.

I'd try other tracers, such as client_channel, client_channel_routing, cares_resolver etc. The "No error" message is an internal thing and has nothing to do with whether the call as a whole has succeeded. You should also specify which platform and grpc version you're using.
