on-premises data gateway (personal mode) SQL server basic login not working

[bfrancis]

I installed the latest On-premises data gateway (personal mode) today and a SQL server database I had been successfully connecting to with the previous version (Power BI gateway - personal) is no longer working.  Specifically, I cannot connect to the server's database using the "Basic" login mode.  This has worked flawlessly since the first versions of the personal DMG, so something has clearly been broken.  Also, I am able to connect to other data sources (databases) in the same server using Windows authentication mode.  So, the problem is with "Basic" login mode.

This is a serious issue for us since many reports being refreshed use this data source.  Anyone else experiencing this problem?  Any suggestions on how to resolve?

Thanks,

Bob
