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 ,
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.

Hope it helps!

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.
