1. A screenshot of the error message.
2. Does the data update successfully if using Tableau Desktop on the same machine as Tableau Server?
3. Does the data update successfully using Tableau Desktop 8.2.
4. Do you have the same driver installed on both the Tableau Desktop and the Tableau Server machine?
