# Troubleshooting

If you encounter issues while configuring or querying the [**Kentik Connect Datasource**](/v1/docs/grafana) for Grafana, review the common error codes and solutions below.

## Common Error Codes

### **404: Dashboard or Plugin Not Found**

- **Legacy App Links:** If you recently migrated and are clicking old bookmarks for the `kentik-connect-app`, those pages no longer exist.
  - **Fix**: Navigate to the **Dashboards** tab of the new data source configuration to [**import the updated dashboards**](/v1/docs/migrate-to-v2-data-source#migration-steps-for-existing-users).
- **Grafana 13.0.0+ Routing Issue:** If you are using version 2.0.0 of the Kentik plugin on Grafana 13.0.0 or newer, you may encounter a bug where panels fail to load and unexpectedly return a “404 Not Found” error.
  - **Fix:** Update the `kentik-connect-datasource` plugin to **v2.0.1** or higher.

### **500: Internal Server Error / Authentication Failures**

- **SSO Organizations:** Historically, organizations enforcing Single Sign-On (SSO) experienced 500 errors with the legacy v1.7.0 plugin.
  - **Fix:** The v2.0.x data source architecture resolves these SSO authentication drops. Ensure you have fully migrated to the v2.0.x plugin and that the API token provided belongs to an active user with the correct query permissions.

### **400: Bad Request**

- This typically indicates a syntax error in your query or an invalid dimension combination.
  - **Fix:** Review the query editor parameters. Ensure that you are not attempting to query NMS metrics (like SNMP interface counters or device health), as the current version of the plugin exclusively supports Flow data and dimensions.
