No Open Port Found

Why This Error Occurred

Your application code exited or timed out before binding to a port number.

Possible Ways to Fix It

  • For Node.js deployments, a call to Server#listen() might be missing.
  • For Docker deployments, there might be a mismatch from what the EXPOSE directive specifies compared to what your application binds to.
