Hello, i'm just trying to list my s3 buckets on node red, and I wrote a simple node js application:

```auto
var AWS = global.get('aws-sdk');
var ep = new AWS.Endpoint('http://localhost:4566');
var s3 = new AWS.S3({endpoint:ep});

s3.listBuckets(function(err,data){
    if(err) console.log(err,err.stack);
    else console.log(data.Buckets);
});

```

It works when i run `node app.js` siply from bash, but If i try to run it on a function node in node-red, I get this error:

```auto

    }
  }
} Error: connect ECONNREFUSED 169.254.169.254:80
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1159:16)

```

I tried debugging it and the endpoint looks correctly configured. I should mention I'm running both node-red and localstack through docker, and they are connected to the same docker network.

Solved the problem: basically I tried to refer to localhost from within the container so obviously it tried to access the wrong resource. All I had to do was change from  
`http://localhost:4566`  
to  
`http://localstackContainerName:4566`

Looks like many of us face this type of connection problems with localstack. I faced issues while connecting to SQS using localstack. I needed to change the docker-compose setup of localhost container to fix it.
