Help with Power BI scheduled refresh failure - Snowflake connecttion

Hi , SreePeri 

According to your error description and your error message provision, this refresh error is caused by a problem with the gateway server and your Snowflake connection, and then the specific error message prompt is "Couldn't resolve host name", For whether the Snowflake warehouse data source has been opened before the data refresh, I think you need to determine in advance before the data refresh starts. To determine whether this error message is enabled or encountered, you need to collect the additional log of the gateway at the time of the error and the detailed error log of the Snowflake warehouse data source for in-depth analysis.

For information on how to collect some additional logs of the gateway, please refer to this official document:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
