Hi @VladimirZD,
With gRPC services to properly load balance the requests, you should be setting the gRPC services protocol type to grpc
using a service-defaults
config entry.
ref: Service defaults configuration entry reference | Consul | HashiCorp Developer
In your case, you will have to apply a config entry as shown below:
Kind = "service-defaults"
Name = "grpcservice"
Protocol = "grpc"
Once you apply this, if still the requests are not spread, make sure you restart the downstream application.
Please let me know if this works for you.
