I am new to Dremio, and trying to connect Dremio 1.2.1 to Tableau via ODBC with my admin account. I followed the instructions [https://docs.dremio.com/drivers/dremio-connector.html](https://docs.dremio.com/drivers/dremio-connector.html) However, the error message persists. "[Dremio] [Connector] (20) Failure occurred while trying to connect to local=localhost:9047" Is this a known issue with the new version? Or this is something wrong with my computer environment? Looking forward to any comments or suggestions. Thanks ---

If you just downloaded Dremio and rely on the default configuration, port 9047 is used for the UI, and you usually connect to it using a browser. The default port for ODBC/JDBC client is 31010 (can be configured to a different port). This should be the default when creating a new DSN, or when connecting from Tableau using directly the driver.
