Hi @valefar, Firstly, ensure your connection settings correctly map the server's endpoint to 'localhost' and the appropriate port number through the proxy service. Double-check your connection string or configuration to align with Databricks workspace details. If connecting to a SQL Server database, confirm you're using the correct JDBC URL format with the port set to 1433. Validate that the proxy service is forwarding requests correctly and handling any required authentication or authorization. Verify ODBC driver settings, ensuring the hostname and port are correctly configured. Enable detailed logging to review any specific error messages or unexpected server responses. Test each adjustment carefully, and if issues persist, let me know.
