I am just getting started with Stellar. I run a node connected with test network with the following command.

docker run --rm -it -p "8000:8000" -v "/home/prashant/stellar/steler-node:/opt/stellar" --name stellar stellar/quickstart --testnet

I created an account and received some Lumens using friendbot.

Now when I try to connect to horizon using npm request module. I am able to query balance. This script works perfectly.

const request = require('request-promise');

const options = {
  method: 'GET',
  uri: 'http://localhost:8000/accounts/GD7HLQRVOFPYJBQ4HJY74LJZ5FXM5YPTZA55IKXZNSEPLF7UYEWDBJ4G',
  json: true // keep this true else you need to parse the response

        //account = JSON.parse(response);
        console.log('Balances for account: ' + account.account_id);
        account.balances.forEach(function(balance) {
          console.log('Type:', balance.asset_type, ', Balance:', balance.balance);
        console.log("Unable to get balance.");

But when I try to connect using SDK, check following script.

var StellarSdk = require('stellar-sdk');

const account1 = {

var server = new StellarSdk.Server('');

// the JS SDK uses promises for most actions, such as retrieving an account
server.loadAccount(account1.publicKey).then(function(account) {
  console.log('Balances for account: ' + account1.publicKey);
  account.balances.forEach(function(balance) {
    console.log('Type:', balance.asset_type, ', Balance:', balance.balance);
    console.log("error occured in getting balance");

I get error:

error occured in getting balance { Error: write EPROTO 139981321324352:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:../deps/openssl/openssl/ssl/s23_clnt.c:827:

at _errnoException (util.js:999:13)
at WriteWrap.afterWrite [as oncomplete] (net.js:883:14) errno: 'EPROTO', code: 'EPROTO', syscall: 'write' }

However I have tested the later script connecting to setller's test node : https://horizon-testnet.stellar.org and it worked like charm.

Did I miss anything while setting up the node? Or I am calling the functions in wrong way?

Edit 1: I tried using https in my url to horizon. I got hit by error:

throw new Error("Cannot connect to insecure horizon server");

  • Public net horizon is currently down at the time of this comment, maybe that is the problem? – Ron Serruya Feb 28 '18 at 9:33
  • I am not trying to connect to public net horizon. I am trying to connect to my own node. – Prashant Prabhakar Singh Feb 28 '18 at 9:44

Okay. So found the solution with help of @Bartek Nowotarski.

My local horizon didn't have SSL certificate. So I had to either

  • add SSL to the horizon
  • Use it without SSL: var server = new StellarSdk.Server('', {allowHttp: true});

Not sure why this was not documented anywhere.
