We are using the [ADO.Net](http://ADO.Net) QuickBooks Online driver which we have used for many years. Recently we are no longer able to connect with the QBO Profit and Loss statement. We are able to connect with the Balance Sheet. The line of code that it’s erring on is this:  
Using rdr2 As QuickBooksOnlineDataReader = cmdIS2.ExecuteReader()

Here is what I’ve done:  
1. Tried on both Windows 11 and 10 computers  
2. Reviewed&nbsp;the schema file&nbsp;  
3. Examined the log file (verbosity 5) - here’s a snippet  
2025-03-12T09:34:39.693-07:00&nbsp;&nbsp; &nbsp;2&nbsp;&nbsp; &nbsp;[&nbsp; 13| &nbsp; &nbsp;5| &nbsp; 38]&nbsp;&nbsp; &nbsp;[HTTP|Res: 17] HTTP/1.1 406 Not Acceptable, 0 Bytes Transferred

&nbsp; &nbsp;at rno240u.AF.lF(String )

If anyone has any suggestions, I’d appreciate your thoughts.

Thanks,

Sally
