No success in reaching to external host

[rmdzetc]

I have pulled the latest in master branch. I can not hit the gRPC server (external).

1. I have replaced localhost and port with host ip and port
2. I have added a new protofile under karate-grpc-proto (i can get list with the same proto)
3. I have tried running all tests via mvn install
   Do you have any idea why it does not work? Below is the error I get.

01: client.call('textservice.Text/Generate', payload, karate)
