Stats API Temporarily Down

[duckducknono]

System information

Geth version: Version: 1.10.1-stable Git Commit: c2d2f4ed8f232bb11663a1b01a2e578aa22f24bd Architecture: amd64 Go Version: go1.16

Redis version: Redis server v=3.0.6

OS & Version: LINUX VERSION="16.04.7 LTS (Xenial Xerus)

Expected behaviour

Static homepage to deploy correctly as opposed to application-error.hbs

Actual behaviour

The homepage/root page, through nGinx is displaying a stats unavailable page. Statistics are showing on /api/stats however despite altering the ApiUrl in environment.js, config.json and checking nginx configurations nothing seems to be taking a hold. I have make cleaned and rebuilt on numerous occasion.

I have noticed in dev console that 'stats' asset is 404'ing due to a 'doubled up' destination URL (the server public IP is displaying twice concatenated).

The rebuilds of environment/js configurations don't seem to be taking effect and it seems like the configurations are cached somewhere.

Geth is successfully syncing and mining as well as the pool running successfully.

Steps to reproduce the behaviour

What does your nginx & pool configs look like (with sensitive info removed)?

http://104.238.171.71/104.238.171.71:80api/stats Looks like it is just a simple misconfiguration. Should be able to tell once I see the configs

ENVIRONMENT.JS

/* jshint node: true */

module.exports = function(environment) {
  var ENV = {
    modulePrefix: 'open-ethereum-pool',
    environment: environment,
    rootURL: '/',
    locationType: 'hash',
    EmberENV: {
      FEATURES: {
        // Here you can enable experimental features on an ember canary build
        // e.g. 'with-controller': true
      }
    },

    APP: {
      // API host and port
      ApiUrl: 'http://104.238.171.71/',

      // HTTP mining endpoint
      HttpHost: 'http://example.net',
      HttpPort: 8888,

      // Stratum mining endpoint
      StratumHost: 'example.net',
      StratumPort: 8008,

      // Fee and payout details
      PoolFee: '1%',
      PayoutThreshold: '0.5 Ether',

      // For network hashrate (change for your favourite fork)
      BlockTime: 14.4
    }
  };

  if (environment === 'development') {
    /* Override ApiUrl just for development, while you are customizing
      frontend markup and css theme on your workstation.
    */
    ENV.APP.ApiUrl = 'http://127.0.0.1:8080/'

I realise that the other settings have example.net in them as I have just attempted to put the configs back to originals.

My issues is that the the IP error in dev console never seems to change despite rebuilding.

Thanks for your help!

Just to verify, you ran ./build.sh after making the changes to open ethereum pool config? And did a nginx reload after making changes to the nginx configs?

[duckducknono]

Yeah 100% - I've just done a rebuild and restarted again just in case.

I've been through iterations of changing both environment.js and config.json to try and spot changes in the destination error in console but this 'http://104.238.171.71/104.238.171.71:80api/stats' never seems to change. I was wondering if a built file had the potential to hold that IP and doesn't get overwritten after rebuilding? Not entirely sure....

If you're confident the above configurations look correct that I may have to build again from scratch.

[mikeyb]

The configs do seem correct to me. Are there any errors when running build.sh? If you redo the install and still run into issues, I would be willing to jump on the server and take a look at things if you like.

[duckducknono]

There are a few warnings yes - they are related to the API, too, although I had just assumed it was a deprecation thing given all the random package versions I'm using.

OK - well I'll probably try and have a rebuild tomorrow and see if that resolves anything. Thanks for your help - greatly appreciated!

Hi team, I see this same error on my server , I have been trying to troubleshoot for several days so far. I think it might be related to a permission error, did you find the issue? Please share, thanks a lot

[tatuiot]

Hi team... I finally after so much testing... the fix was the following in open-etc-pool/www/config/environment.js relpace localhost to server address the ENV.APP.ApiUrl entry.
