Power BI Server Refresh issues

Pyelamanchili — Fri, 20 Mar 2026 16:40:46 GMT

Hello All,

I have a Power BI Report that conneccts to Snowflake through KeyPair.

It refreshes in my desktop without any errors. However on the server it runs through gateway, and failes to refresh with the error below.

One think I can confirm is, Desktop and Server runs on the same credentials and this Snowflake role has access to all the tables/views.

I have already looked into the Implementation2.0 and it did not resolve the issue.

Any help is appreciated.

Thanks!

Temporarily install Power BI Desktop on one of your gateway VMs (don't forget to remove it afterwards) . Then try to connect to your data source from that Power BI Desktop. See if you get an error message.

Thanks for the response. MY gateway is set up by the Admin team. However, most cases you can change the ADBC to ODBC by removing Implemantation 2.0 from you MQuery!

However that did not work for me. Trying the other ways

Hi @Pyelamanchili

Thank you for contacting the Microsoft Fabric community forum.

The issue is linked to the gateway execution environment, not Snowflake permissions.When a dataset refresh occurs in Power BI Service, the gateway’s mashup engine executes queries, which is different from the local Desktop engine. Due to differences in runtime, drivers, and execution context, refresh results can vary between Desktop and Service. More details are available here:https://learn.microsoft.com/power-bi/connect-data/refresh-troubleshooting-refresh-scenarios

While removing Implementation="2.0" may help in some Snowflake scenarios, it doesn't always impact how the gateway processes connections, so it did not resolve this issue. Please check the gateway setup to ensure it is correct. The on-premises data gateway should be up to date, and the Snowflake data source must be fully configured with all required settings like server, warehouse, and role. Mismatched or incomplete configurations can still cause refresh failures, even if Desktop works as expected:https://learn.microsoft.com/power-bi/connect-data/service-gateway-onprem

It’s also important to consider how the private key is accessed. The gateway operates under a Windows service account, so if the key is stored locally or in a restricted folder, it might not be accessible during refresh, even if it works in Power BI Desktop. Ensure the key is in PKCS#8 format, set up correctly in Power BI Service, and available to the gateway service account.

Finally, confirm that the Snowflake driver on the gateway machine is current and supported, as driver differences can affect refreshes.Power Query Snowflake connector - Power Query | Microsoft Learn

Hello,

Sorry for the delayed response. I have tried these but nothing worked.

But while digging through, I understand the issue is with the Keypair Update on snowflake account.

For Power BI (Desktop, cloud, gateway) Snowflake Account has to be TYPE= PERSONAL.

Snowflake account TYPE = LEGACY_SERVICE /SERVICE is not supported for KeyPair Authentication.

My snowflake was set to LEGACY_SERVICE, whick is a potential reason for the failures.
