Next.js deploys, but the app is unreachable

If the build passes and the URL still fails, Next.js is either not listening where the platform expects or it crashed while starting.

Check the logs

An exception here means the app crashed at boot. A missing variable is a common reason.

next start uses the PORT and HOSTNAME values EasyHost sets. If you wrote a custom server, pass both to listen yourself.

package.json

{
  "scripts": {
    "build": "next build",
    "start": "next start"
  }
}

Next.js starts with scripts.start, or next start -H 0.0.0.0 -p $PORT when no start script exists.
