Node.js HTTP GET “ECONNRESET” Error on read

Question

I've read all the related issues on SO and GitHub about this error and none of them seem to address this situation.

When I run the following code:

response = await axios.get('http://localhost:8082/panda, {
  httpAgent: new http.Agent({ keepAlive: true, keepAliveMsecs: 10000 })
});

I get the following error:

{ Error: socket hang up
    at createHangUpError (_http_client.js:345:15)
    at Socket.socketOnEnd (_http_client.js:437:23)
    at emitNone (events.js:110:20)
    at Socket.emit (events.js:207:7)
    at endReadableNT (_stream_readable.js:1059:12)
    at _combinedTickCallback (internal/process/next_tick.js:138:11)
    at process._tickCallback (internal/process/next_tick.js:180:9) code: 'ECONNRESET' }
{ Error: read ECONNRESET
    at _errnoException (util.js:1019:11)
    at TCP.onread (net.js:608:25)
  code: 'ECONNRESET',
  errno: 'ECONNRESET',
  syscall: 'read',
  etc...

There's no stack trace beyond the onread call so it's unclear how I can get any additional information beyond the ECONNRESET error code (-54) passed to the onread method in net.js

This issue happens with every request - it is not intermittent.

A few observations:

• when making the same request from chrome or postman the request does NOT fail
• attempting to reproduce a successful request from Chrome, by using the same headers, fails
• setting the accept header to use 'gzip', etc.. does not help - I have tried all the recommendations including some weird ones like setting the content length and adding a body to the request despite this being a GET request
  • the error always appears in net.js, but happens with both the request and axios libraries

Here's the interesting part - I can only seem to reproduce this problem reliably when I am hosting the server locally. I am able to reach the dev instance or run the server in vagrant, via a docker container, without issue.

I am running macOS Sierra 10.12.6 if that makes any difference. The server is written in Java and uses the Spring framework. Here is the RestTemplate configuration I'm using for HTTP calls:

@Bean
public RestTemplate restTemplate() {
    //request timeout
    int timeout = 5000;

    //Connection Pooling factory with timeouts to prevent disastrous request responses
    HttpComponentsClientHttpRequestFactory cf = new HttpComponentsClientHttpRequestFactory();
    cf.setReadTimeout(timeout);
    cf.setConnectTimeout(timeout);
    cf.setConnectionRequestTimeout(timeout);

    return new RestTemplate(cf);
}

I've tried messing around with these settings with no luck.

Any ideas?

Answer 1

I have the same issue. The cause was in my proxy settings. I make proxy-port localhost:8080 to my localhost:3000. That's why all API requests from my NodeJS app to localhost:3000 returned "ECONNRESET" Error. When I delete proxy-port, the issue was resolved. Check your net settings. Maybe it's redirecting problem

This was a known issue with NodeJS and has been resolved. Please see http.Agent: idle sockets throw unhandled ECONNRESET for details.

Also ensure you have enabled the correct security settings when opening a port on MacOS
