A clear path forward

My app works in the editor preview but not when published—why?

A difference between preview and production settings can stop an app from working after publishing.

Compare these settings:

  • Secrets: check that all required keys are present in the deployment secrets, not only in development. These are separate environments.
  • Database: if your app uses a database, check that DATABASE_URL points to production rather than development.
  • Request addresses: remove hard-coded localhost or 127.0.0.1 references. Use relative paths or environment-based addresses appropriate to where the code runs.

Then check the deployment logs for production-specific errors. See Secrets and Troubleshooting deployments.
