  ### Common Issues Matrix

  | Symptom | Likely Cause | Quick Fix |

  |---------|--------------|-----------|

  | Image pull failure | ACR credentials missing | `az containerapp registry set
  --identity system` |

  | ACR build fails | ACR Tasks disabled (free sub) | Build locally with Docker
  |

  | Cold start timeout | min-replicas=0 | `az containerapp update --min-replicas
  1` |

  | Port mismatch | Wrong target port | Check Dockerfile EXPOSE matches ingress
  |

  | App keeps restarting | Health probe failing | Verify `/health` endpoint |
