I think I've stepped at this one day. I think it was related to docker and by default it doesn't set an ipv6 address.

If is it, you probably will find a way to fix here: https://docs.docker.com/v17.09/engine/userguide/networking/default_network/ipv6/

I can not connect to the rpc from local machine.
I am using rpcauth and the error is:
ERROR Request Error: socket hang up

var run = function() {
var RpcClient = require('bitcoind-rpc');

var config = {
protocol: 'http',
host: '0.0.0.0',
port: '18332',
username: 'jelly',
password: '84k_0ftqUEcciE5hd4rd2pD0FxEreoizsf8ec5Mh_oI='
};

// config can also be an url, e.g.:
// var config = 'http://user:pass@127.0.0.1:18332';

var rpc = new RpcClient(config);
var txids = [];

function showNewTransactions() {
rpc.getRawMemPool(function (err, ret) {
if (err) {
console.error(err);
return setTimeout(showNewTransactions, 10000);
}

  function batchCall() {
    ret.result.forEach(function (txid) {
      if (txids.indexOf(txid) === -1) {
        rpc.getRawTransaction(txid);
      }
    });
  }

  rpc.batch(batchCall, function(err, rawtxs) {
    if (err) {
      console.error(err);
      return setTimeout(showNewTransactions, 10000);
    }

    rawtxs.map(function (rawtx) {
      console.log('\n\n\n' + rawtx  + ':',);
    });

    txids = ret.result;
    setTimeout(showNewTransactions, 2500);
  });
});

}

showNewTransactions();
};

run();

@senhanxiao that does not create any problem unless you're trying to connect using ipv6 as mentioned by @victorperin.

@tima-t you are probably hitting the issue reported and fixed by #85.
