Re: Data Flow Authentication issue against Azure SQL DWH

Hi @abhiram342 ,


First of all, we suggest you to delete the information of database in your origin post.


Could you please try to connecting to this Azure SQL DW with the exact same credential in a new Data Flow? Does there have any Firewall rules update after 01/17/2020 with this Azure SQL DW ?

Best regards,
