+## Troubleshooting manifest-related alerts
+
+When you encounter manifest-related alerts such as `UNPARSABLE_MANIFEST`, `VARIANT_DURATION_MISMATCH`, or `TARGET_DURATION_MISMATCH`, check the following:
+
+  1. **Verify source requirements** : Ensure your content meets the requirements outlined in [Integrating a content source for MediaTailor ad insertion](./integrating-origin.html).
+
+  2. **Check manifest logs** : For detailed manifest error analysis and event types, see [AWS Elemental MediaTailor manifest logs description and event types](./log-types.html).
+
+  3. **Check error codes** : For detailed error analysis, see [Troubleshooting MediaTailor](./troubleshooting.html).
+
+  4. **Review manifest format** : Verify that your manifest follows the correct format specifications for your streaming protocol (HLS or DASH).
