I am new to tableau and online/server. I have created several dashboards with different data sources (6 in total) through SQL. The extracts refresh via the tableau bridge and have been refreshing daily without issue until recently. The data sources are now not refreshing automatically and when i go to manually refresh errors appear with the details as follows "unable to refresh bridge - connected data source".
If anyone could advise what the issue is and how to get around that would be appreciated.
