We are running "helloworld" example from https://grpc.io/docs/quickstart/cpp.html#update-a-grpc-service and we received the following ERROR:
14: Connect Failed
Greeter received: RPC failed.
The server and the client are listening on: 0.0.0.0:50051. The Server is running.
First we receive just a packet on the server and the client crashes, I checked it with tcpdump. We checked on different hosts as well as on the same host but it didn't work for either cases.
Should we change a different IP or different Port number?
