Power BI Gateway. "A specified logon session does not exist"
I found a workaround. The connection works when using Dataflows and Azure Analysis Services, as it allows selecting "Basic" as the authentication kind.
Hi PeterSdobyrev ,
What operation are you performing that is giving you the error. There are a few things that are not quite clear to me about your description. First of all you're connecting directly, which usually doesn't require a gateway. Secondly, you are connecting to a table model, when you create the connection the data source should not be selected Sql server it should be AS.
Hope it helps!

The error only occurs when I publish the report to the Power BI Service and configure the connection to Analysis Services through the gateway. When I connect directly to Analysis Services from Power BI Desktop during dashboard development, there’s no issue, and I can connect without error.
Let me know if you'd like to expand on any details!
Hi PeterSdobyrev ,
If this error is reported when opening a report or dashboard, try to map user.The email address must match a defined user principal name (UPN) within the local Active Directory (AD) domain. The UPN is a property of an AD account. The Windows account must be present in an Analysis Services role.

I’ve checked the UPN mapping, AD setup, and ensured the Windows account is in the correct Analysis Services role. Unfortunately, the issue still persists.
