Hi all,
I'm trying to fix following problem since five days.
When I'm doing a

or

  • http.get(options, cb);

there's this error coming back:

HTTP 5021: SOCKET ERROR: getaddrinfo ENOTFOUND _host_ _host_:80 Error: getaddrinfo ENOTFOUND _url_ _url_:80
    at errnoException (dns.js:26:10)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:77:26)
Got error: getaddrinfo ENOTFOUND _host_ _host_:80
NET 5021: destroy undefined
NET 5021: destroy
NET 5021: close
NET 5021: close handle

NET 5021: emit close
HTTP 5021: CLIENT socket onClose
HTTP 5021: removeSocket _host_:80: destroyed: true
HTTP 5021: HTTP socket close

When doing a https request to google.com:
Got error: connect ENETUNREACH 2a00:1450:400a:806::1014:443 - Local (:::0)

I can definitely say it's NOT a DNS or a PROXY issue.

What I testet so far:

  • changed hosts file, so no dns lookup is required

  • changed resolv.conf to use other DNS servers

  • **curl and wget requests do work**

  • **ping to destination host works**

  • reinstalled complete system

  • same node.js code works on a raspbian system

node.js sample code:

var http = require('http');
var options = {
  host: '_host_',
  port: 80,
  path: '/'
};

http.get(options, function(res) {
  console.log("Got response: " + res.statusCode);

  res.on("data", function(chunk) {
    console.log("BODY: " + chunk);
  });
}).on('error', function(e) {
  console.log("Got error: " + e.message);
});
  • Version: v5.5.0
  • Platform: Linux buildroot 4.1.15 armv6l (raspberrypi)

    Just to be clear, you're not actually doing http.get("http://url/", cb); but rather http.get("http://www.google.com/", cb); or some other website that exists - right?

    Also, if you could try previous versions of Node and see if they work for you it would be very appreciated.

    Yes. url and host are just placeholders.

    getaddrinfo is by definition a DNS issue. Does dig host or nslookup host work? Does dns.lookup(host, console.log) work? Can you post the domain?

    dig is not available for buildroot. nslookup is working and gives me the ip address back. I tested lots of different domains (ex. www.hackaday.com)

    and yes, dns.lookup(host, console.log) works and the returned ip address is correct.

    What does dns.lookup(host, {hints: dns.ADDRCONFIG|dns.V4MAPPED}, console.log) print?

    Am I right that it works with {hints:0}? What happens with {hints:dns.ADDRCONFIG} and {hints:dns.V4MAPPED}?

    • {hints:0}

    'x.x.x.x' 4

    • {hints:dns.ADDRCONFIG}

    'x.x.x.x' 4

    • {hints:dns.V4MAPPED}
    { [Error: getaddrinfo ENOTFOUND host]
  code: 'ENOTFOUND',
  errno: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'host' }

    x.x.x.x is the correct IP returned.

    Thanks. You didn't mention what version of glibc you have installed but you're probably hitting a bug in that library. www.hackaday.com is a good example - it's a CNAME for hackaday.com and older glibc versions didn't handle AI_V4MAPPED for such records.

    As a workaround, try http.get({ family: 4, ... }, cb), that tells node not to use AI_V4MAPPED. Use { family: 6 } if you want an IPv6 connection.

    I'm using uclibc 1.0.12. At the moment I'm compiling buildroot with standard glibc. Will tell you if something has changed.
    Setting the family to 4 is working. 6 is giving me back the known errors.

    So, current workaround will be this:

    var options = {
  host: '_host_',
  family: 4,
  port: 80,
  path: '/'
};
http.get(options, cb);

    I cannot compile buildroot with standard glibc. There are too many errors.
    So for now, above workaround will be the best solution for me.

    Okay. And the other applications (like ping) do the same but handle the result for you. Got it. Thanks.

    I don't understand how the "fix" proposed by @bnoordhuis in 2016 is still relevant (or not a default option or documented) 😞

    Easy - if Node.js were to list every random bug you could possibly hit in some third-party library, the documentation would be several times its current size.

    Ok, quick question:

    Assuming

    • we're using https.get (or a similar library such as axios)
    • the domain is legitimately wrong (let's say user error)
    • we need to catch this error in order to return a notice back to the user

    What is the method we should be using?

    No combination of try/catch or .then().catch() is working for me

    Did you try adding an on(‘error’, ...) listener? https://nodejs.org/api/https.html#https_https_get_options_callback

    the solution is simple: go to the IDE copilot extension menu and reinstall the extension

    If your use windows and a proxy service, try to set the system hosts file. Add 127.0.0.1 example.com to the file.
