Shceduled/ On Demand Refresh Failures with Snowflake data sources.
Hi All,
I got my resolution from this post and it is working.

Hi amol_mahajan ,
Random Snowflake refresh errors in Power BI are almost always caused by using shared or global credentials. Here’s what works in real life:
-
Set up a dedicated Snowflake user for each Power BI dataset instead of sharing one login. Session conflicts are super common if you share.
-
If you can, switch from username/password to OAuth or key pair authentication it’s much more reliable, especially with multiple refreshes running.
-
Double-check and re-enter your credentials in Power BI Service settings, just to be sure nothing is cached or expired.
-
If you’re using an on-prem gateway, network hiccups or VPN drops can cause these errors worth checking your gateway logs.
-
As a last resort, try staggering refresh schedules if you’re stuck sharing an account, but honestly, dedicated users and stable auth methods are the real fix.
