Heroku returns "Error: listen EADDRNOTAVAIL: address not available" on starting Strapi CMS

I am trying to deploy Strapi on Heroku

But it does not work. I get this log

Not sure if it's what @Rochadsouza meant, but I got the same error and what finally solved the issue in my case was to set the host to 0.0.0.0. For some reasons, the host cannot be the app url, it needs to allow all hosts on Heroku. I was setting the host in server.js using env('HOST', '0.0.0.0') but had the HOST env var set to my app url on Heroku...

Hope it saves some time to others facing the same error.

I had to change server.js file (port 443):

module.exports = ({ env }) => ({
  host: env('HOST', '0.0.0.0'),
  port: env.int('PORT', 443),
  admin: {
    auth: {
      secret: env('ADMIN_JWT_SECRET'),
    },
  },
});

My database.js file:

module.exports = ({ env }) => ({
  defaultConnection: "default",
  connections: {
    default: {
      connector: "mongoose",
      settings: {
        uri: env("DATABASE_URI"),
        ssl: { rejectUnauthorized: false }
      },
      options: {
        ssl: true,
        authenticationDatabase: "",
        useUnifiedTopology: true,
        pool: {
          min: 0,
          max: 10,
          idleTimeoutMillis: 30000,
          createTimeoutMillis: 30000,
          acquireTimeoutMillis: 30000
        }
      },
    },
  },
});

I hope it will help to somebody who has the same problem :-)

Which is the value of process.env.HOST. For some reason different from 0.0.0.0 (just a shot in the dark - https://strapi.io/documentation/3.0.0-beta.x/migration-guide/migration-guide-beta.19-to-beta.19.4.html#listened-host-changed)
