**Troubleshooting Tips**

1. **Connection Issues**: Double-check the credentials and ensure your ClickHouse instance is accessible.
2. **Firewall Rules**: If your ClickHouse DB is hosted in a secure environment, confirm that Jet Admin's IP addresses are whitelisted.
3. **SSL/TLS**: If your database requires encrypted connections, ensure SSL/TLS settings are correctly configured in ClickHouse and Jet Admin.
4. **Port Issues**: For ClickHouse, you need the **native connection type**. The default port for the native protocol with SSL/TLS is **9440**.&#x20;
   * Make sure to use **native protocol SSL/TLS port**.
   * Refer to ClickHouse documentation for more details: [ClickHouse Network Ports](https://clickhouse.com/docs/en/guides/sre/network-ports).
