I have a published Power BI Report that points to a SSAS Tabular database. It worked fine for an extended time up until we updated the password on the admin account. Now the report is blank and shows a pink bar at the top that says "There was a data source access error. Please contact the gateway administrator." I updated the password on the data source in the gateway and it says "Connection Succesful". I have tried the following but still have a blank report.
- I have updated the gateway and I have restarted the gateway.
- I confirmed that the admin account is assigned to a role on the database using the exact same account
- I removed the data source from the gateway completely, then added it again (Connection Successful), then mapped the dataset to that data source.
- I can connect successfully to the data source in Power BI Desktop using the same credentials
- I restarted the server that houses both the gateway and the SSAS Tabular database
- I tried creating a new report pointing to the same SSAS Tabular database and published to the service. I mapped it to the data source, but it has the same error when I try to view the report.
Can this be a UPN issue considering that nothing has changed except for the password? Is there somewhere that I need to update credentials?
