Microsoft EmployeePower BI Report Server October 2020 update has been released.
Upgraded Power BI Report Server and confirmed Version: 1.9.7627.11028 is now installed.
Chose Manage for an existing report then confirmed Data Sources credentials are correct and connection tested successfully. Attempted a Refresh Now and received this error:
SessionID: 6bbca19a-154f-4758-bb4c-a62cbbe06ae3
[0] -1056505856: COM error: Microsoft.PowerBI.ReportServer.ASEngineManagedRoot, No credentials were found for the datasource.
[1] -1056505856: COM error: Microsoft.PowerBI.ReportServer.ASEngineManagedRoot, No credentials were found for the datasource.
[2] -1055784828: The database operation was cancelled because of an earlier failure.
Installed Microsoft Power BI Desktop (October 2020) (x64) version 2.86.1321.0. Chose Edit in Power BI Desktop and Refreshed All. Confirmed data refreshed, saved, and closed. Succesfully tested credentials again, and attempted to Refresh Now, only to receive similar error. Tested reports with Teradata data sources then tested with Vertica sources using direct connection and ODBC. All fail with error regarding "No credentials were found for the datasource."
Still have hundreds of unhappy users with non-working reports in a corporate environment.

We also have the same problem. everything works good except when we schedule refresh the reports. Then we receive meaningless errors like "Data source not found", "Credintioals are not correct", "There is no data available in the database" or even "An element with the same key has already been added"
