Hi,
This is my first experience with deployment grpc. I have this problem when
I run my client on different machine of the server:
Exception in thread "main" io.grpc.StatusRuntimeException: UNAVAILABLE: io
exception

My code of client is :
ManagedChannel channel = ManagedChannelBuilder.forAddress
("localhost",port).usePlaintext().build();
// stubs - generate from proto
ServiceGrpc.ServiceBlockingStub stub = ServiceGrpc.newBlockingStub(channel);
VoloOK.MessageLogin ml = VoloOK.MessageLogin.newBuilder
().setUsername("...").setPassword("...").build();
VoloOK.MessageResponse mr = stub.login(ml);
Can I help me, where is the problem?
