Issue with Connection resets and Time outs.

var http = require('http'),
    Redis = require('ioredis'),
    redis = new Redis({host: '<Snipe>', password: '<Snipe>'});

http.createServer(function(request, response) {
     response.writeHead(200, {'Content-Type': 'text/plain'});
     redis.hget('player:3064ce58-a05d-4783-86aa-c700b3e9fc66', 'Rank', function (err, result) { response.end(result); });
}).listen(4546);

process.on('uncaughtException', function(ex) {console.log(ex.stack());});
console.log('SERVER IS NOW ON! :3');

Node logs:

1|server | SERVER IS NOW ON! :3

I also recently stumbled upon this issue when trying to connect to remote redis instances, here are the logs from node:

I am able to connect to a single instance (with port 6379 ) and execute commands using ioredis but not the sentinels, although I can connect to the sentinels using medis, any idea what the problem could be?

It seems to be a network problem. Are you able to connect to your redis instance via redis-cli?
