Not able to connect to grpc from nodejs/python client

Question

My grpc server is in go (go-micro), and it working fine, I have tested both via micro web and go web app (iris).

This is a local grpc setup

I keep getting this error (Stream removed)

{ Error: 2 UNKNOWN: Stream removed
    at new createStatusError ([projectROOT]/node_modules/grpc/src/client.js:64:15)
    at [projectROOT]/node_modules/grpc/src/client.js:583:15
  code: 2,
  metadata: Metadata { _internal_repr: {} },
  details: 'Stream removed' }

and sometimes I get this error (Trying to connect an http1.x server)

{ Error: 14 UNAVAILABLE: Trying to connect an http1.x server
    at new createStatusError ([projectROOT]/node_modules/grpc/src/client.js:64:15)
    at [projectROOT]/node_modules/grpc/src/client.js:583:15
  code: 14,
  metadata: Metadata { _internal_repr: {} },
  details: 'Trying to connect an http1.x server' }

My Node Code

const grpc = require('grpc');

const AuthPB      = require('./auth_pb');
const AuthService = require('./auth_grpc_pb');

const AuthClient = new AuthService.AuthClient(
    `localhost:59685`,
    grpc.credentials.createInsecure()
);

function run(cb) {
  const AuthTokenRequest = new AuthPB.AuthTokenRequest({
    token: `some token`,
  });
  AuthClient.isLoggedIn(AuthTokenRequest, (err, authRes) => {
    if(!err) return cb({status: 1});
    cb({
      status: 0,
      err,
      message: 'Not loggedin',
    });
  });
}


run(console.log);

I had same error message when client tried create insecure connection but server use ssl

Try to replace

grpc.credentials.createInsecure()

on

grpc.credentials.createSsl()
