Snowflake data source refresh errors following July 2025 release

[reubwork]

In case anyone else finds this. I started getting weird errors refreshing a report in the past few days.

Data source error: The credentials provided for the Snowflake source are invalid. (Source at <service>.). The exception was raised by the IDbCommand interface. Table: <table name>

Testing locally using the same credentials is fine. 

Then I found that the Snowflake connector 2.0 has very recently gone to GA.

Hi @reubwork ,

Thanks for sharing this just trying to better understand your setup so I can offer the right troubleshooting steps. You mentioned the Snowflake refresh is failing in Power BI Service with a credentials error, but it's working fine locally. Just to clarify a few things: are you connecting to Snowflake using OAuth, username/password, or some other method? Are you using a gateway for the dataset, and if so, is it an on-premises or personal gateway? Also, when you say it works locally, do you mean in Power BI Desktop, and does the refresh succeed there without any issues? Did you recently update or republish the report using the July 2025 version of Power BI Desktop? And finally, have you tried re-entering or updating the data source credentials in Power BI Service after the issue started? The reason I ask is that the Snowflake Connector 2.0 just went GA with the July release, and it might have introduced some changes that impact existing configurations, especially around authentication. A bit more info would really help us narrow this down.

We truly appreciate your continued engagement and thank you for being an active and valued member of the community.

We look forward to hearing from you.

Best regards,
Lakshmi
