After a Firebird 3.0 update, our PowerBI Dataset can't find the Firebird database, although the ODBC Setup works just fine.
But the most bizarre part, I can create a new Dataflow-set with the exact same data source (same Gateway to ODBC Source) and it works! I've created a whole new Workspace and uploaded the Dataset/Report into it, the same error occurs.
Some Info:
The ODBC-Source connects to a raw Firebird (main.FDP) database.
A direct connection to the live-Data is not possible, the ODBC-Setup throws an error (File database not found), so I copied the main.FDP into a different folder, that way the ODBC setup connects successfully.
On Power BI Desktop via Power Query Editor, I can see the actual live data, but if I "Close & Apply", the same error occurs (File Database not found) on the refreshing window.
@Mark Rotteveel, thanks for the Solution.
The Solution was the pathing, i added "localhost:[...]" as prefix and it works.
