In Tableau Online Subscriptions intermittently fail with error "Failed to perform data condition evaluation"


  • Tableau Online 2019.3
  • View that uses a live connection to a data source


Please review the data source for the view that Subscription is connecting to and confirm it is able to successfully connect. 

If the root cause of the issue is too many connections to the data source, consider spacing out the number of subscription tasks or scheduling them at times of the day that traffic to the data source may be lower. Alternatively work with your database administrator to allow increased connections to the data source

For additional information see our Help Guide: Troubleshoot Subscriptions


There are multiple potential causes for this error including:
  • Too many connections to the data source preventing the subscription from connecting to the datasource
  • Missing password or invalid credentials in Tableau to connect to the data source.
  • The data source is not accessible at the time the subscription task executed.
