ECONNREFUSED ::1:4400 error even though firestore port and host are explicitly specified #4741

[REQUIRED] Steps to reproduce

Run yarn run test

[REQUIRED] Expected behavior

Expected to exit with code 0

[REQUIRED] Actual behavior

Fails with FetchError: request to http://localhost:4400/emulators failed, reason: connect ECONNREFUSED ::1:4400

This error was introduced in release 11.0.0 and is not present in 10.9.2
Seems like it still tries to find emulators hub, even though host and port for firestore are explicitly specified.
Same error can be observed if a flag FIRESTORE_EMULATOR_HOST=127.0.0.1:8080 is passed.

Currently I solved this error in my project by locking firebase-tools to 10.9.2

The text was updated successfully, but these errors were encountered:

bkendall · 2022-07-14T16:34:15Z

Alright, so this is known, but hard to address fully.

In short, it has to do with how DNS on a machine is being resolved in Node. Most of the emulators bind to the ipv4 addresses, but if a process resolves localhost to the ipv6 address [::1] that can cause the connections to fail (since emulators don't tend to bind on the ipv6 address).

@yuchenshi has been looking into addressing this in a couple places around the emulators. Working on addressing this, but it's been difficult.

augustmuir · 2022-07-18T02:37:48Z

Same issue here on latest version, downgrade to 10.9.2 solved the problem. This is the error message of ui-debug.log when I tried running the latest version:

u [FetchError]: request to http://localhost:4400/emulators failed, reason: connect ECONNREFUSED ::1:4400
    at ClientRequest.<anonymous> (C:\Users\august\.cache\firebase\emulators\ui-v1.7.0\server.bundle.js:326:16909)

    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  type: 'system',
  errno: 'ECONNREFUSED',
  code: 'ECONNREFUSED'
}

I feel like if there was a option to change the Hub port it might resolve this as I've seen the same error before when using a "blocked" port, and it was solved by using another.

What is the preferred method to downgrade firebase globally?

yuchenshi · 2022-07-18T19:53:13Z

~~Fixed in v11.3.0.~~

yuchenshi · 2022-07-18T19:55:14Z

Whoops, wrong issue -- sorry for the confusion. We've fixed some other issues related to Emulator UI, not Emulator hub (used in testing).

yuchenshi · 2022-07-18T19:58:52Z

While we work on this, I think a better workaround than downgrading Firebase CLI is specifying the hub address explicitly using IPv4:

e.g. change the command:

firebase emulators:exec --only firestore \"FIREBASE_EMULATOR_HUB=127.0.0.1:4400 yarn test:mocha\"

Or in configuration:

  env = await firebaseTesting.initializeTestEnvironment({
    projectId: "demo-project",
    /* firestore and other emulators omitted, new hub options below */
    hub: {
      host: "127.0.0.1",
      port: 4400,
    },
  });

valle-xyz · 2022-07-19T07:44:21Z

👏🦾❤️

Upgrading to 11.3.0 fixed this for me! Thanks, @yuchenshi !

kris-kolve-jumio · 2022-08-12T20:33:51Z

setting the Hub host resolved the ECONNREFUSED error for me however, now every test I run storage tests... all the test time out using Mocha at 20seconds.

If I set the storage configuration with host: "127.0.0.1", port:9199, I can get tests with getDownloadURL() to complete appropriately. However, tests with uploadBytes still timeout.

In fact I am not able to get any upload statements to work with the emulators!

yuchenshi · 2022-08-15T20:22:36Z

@kris-kolve-jumio Would you mind opening a different issue for the storage emulator timeout?

Hi all, we've updated how the emulator listens on ports in v11.14.2 and we believe it now should work for most cases (including the OP's repro, quickstart-testing, emulators-codelab, etc.) without any need of workarounds. Please let us know if this isn't the case for you even after the upgrade.

To provide more details, we've changed the Emulator Hub to listen on both IPv4 and IPv6 address by default (if possible) (#5088), and the discovery now returns 127.0.0.1 (IPv4) instead of the ambiguous localhost (which may resolve to IPv6 on Node.js 18+) for other emulators (#5083). These changes together should prevent ECONNREFUSED ::1:4400 and remove the need to explicitly specify host for anything other than the hub. Feel free to dig into the PRs if you're interested in the technical details.

modosc · 2022-10-11T21:54:44Z

hi @yuchenshi - v11.14.2 doesn't work for us in docker.

with this config:

{
  "firestore": {
    "rules": "firestore.rules"
  },
  "emulators": {
    "firestore": {
      "port": 8080,
      "host": "0.0.0.0"
    },
    "pubsub": {
      "port": 8085,
      "host": "0.0.0.0"
    },
    "ui": {
      "enabled": true,
      "port": 4000,
      "host": "0.0.0.0"
    }
  }
}

we get:

[debug] [2022-10-11T21:45:42.494Z] Error: listen EADDRNOTAVAIL: address not available ::1:4400
    at Server.setupListenHandle [as _listen2] (node:net:1415:21)
    at listenInCluster (node:net:1480:12)
    at doListen (node:net:1629:7)
    at processTicksAndRejections (node:internal/process/task_queues:84:21)

and adding this block:

    "hub": {
      "host": "0.0.0.0",
      "port": 4400
    }

gives us a new failure:

[debug] [2022-10-11T21:53:45.578Z] Error: listen EADDRNOTAVAIL: address not available ::1:4500

yuchenshi · 2022-10-12T01:07:01Z

@modosc Thanks for the follow-up. Would it be possible to get the full firebase-debug.log? We'd need to look into where this happens in context and see if we can find a workaround.

yuchenshi · 2022-10-12T01:22:04Z

@modosc I have a guess on what's going on here -- the error may be happening with our new port detection logic and somehow IPv6 isn't available in your Docker network. But we'd still appreciate full logs to confirm this.

Also, if that's the case, I think you can work around this by adding logging too (before we make the next release). Let us know if it works for you.

    "hub": {
      "host": "0.0.0.0",
      "port": 4400
    },
    "logging": {
      "host": "0.0.0.0",
      "port": 4500
    }

fabfuel · 2022-10-12T09:48:32Z

It is a IPv6 issue within the Docker container for us too @yuchenshi

If someone is emulating functions as well, you have to define eventarc's host as well to make it work again:

    "hub": {
      "host": "0.0.0.0",
      "port": 4400
    },
    "logging": {
      "host": "0.0.0.0",
      "port": 4500
    },
    "eventarc": {
      "host": "0.0.0.0",
      "port": 9299
    }

modosc · 2022-10-12T17:00:21Z

i can confirm that adding both of these blocks fixes the issue for us:

    "hub": {
      "host": "0.0.0.0",
      "port": 4400
    },
    "logging": {
      "host": "0.0.0.0",
      "port": 4500
    },

i can also confirm the exact same log output as above. running docker on mac and there's no ipv6 support.

yuchenshi · 2022-10-13T21:12:04Z

EADDRNOTAVAIL should be fixed in v11.14.3 (no workaround needed any more). Thanks for the reports.

joshtemple · 2022-10-26T01:10:32Z

@yuchenshi I'm still encountering this issue in v11.15.0 in Docker. Adding the logging section referenced above to my firebase.json does fix the problem.

greg-md · 2023-04-12T18:40:04Z

The same issue happens inside a github action. Are there any fixes for that? Specifying the host to 0.0.0.0 doesn't help. It still says connect ECONNREFUSED ::1:8080

PS: Downgrading to node 16 fixed the issue.

TRY THIS.
In the packages.json.I think Its from this issue. nodejs/node#41145

So, I added node runtime options in my package.json file like this.
...
"test": "node --experimental-vm-modules --dns-result-order=ipv4first node_modules/jest/bin/jest.js",
"integration:test": "firebase emulators:exec --only firestore,functions --project {PROJECT_ID} "pnpm test""
...

dr-aiuta · 2023-06-23T18:14:43Z

Same issue here, node 18.15.0

christiangenco · 2023-06-27T18:31:24Z

For me the problem was fixed by changing host: localhost to host: 127.0.0.1 in my initializeTestEnvironment function call.

From this:

testEnv = await initializeTestEnvironment({
  projectId: PROJECT_ID,
  firestore: {
    rules: fs.readFileSync("firestore.rules", "utf8"),
    host: "localhost",
    port: 8080,
  },
});

to this:

testEnv = await initializeTestEnvironment({
  projectId: PROJECT_ID,
  firestore: {
    rules: fs.readFileSync("firestore.rules", "utf8"),
    host: "127.0.0.1",
    port: 8080,
  },
});

solution reference firebase/firebase-tools#4741

greg-md · 2023-10-25T12:23:53Z

@gkawin thank you! It worked on node18 by adding NODE_OPTIONS=--dns-result-order=ipv4first.

I have the same issue but is when I use the firestore emulator with the sdk admin in a NextJS app on Mac and adding this to my firebase.json fix the issue
