Remix deploys, but the app is unreachable

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

Check the logs

npx ezhst logs --tail 200

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

remix-serve reads PORT and HOST from the environment. A custom Express server must pass both to listen.

package.json

{
  "scripts": {
    "build": "remix vite:build",
    "start": "remix-serve ./build/server/index.js"
  }
}

Remix starts with scripts.start, usually remix-serve ./build/server/index.js.

npx ezhst build show

Remove platform adapters such as @vercel/remix so your loaders run on the plain Node.js runtime.

See the Remix hub for every Remix guide, or free Remix hosting for what is included.

Install the skill, choose Global or Local, then tell your agent to deploy. No credit card, no config files.
