SSAS Live Connection Failes when refreshing or interacting with visuals

[behnam_ab]

I've setup Active Directory, On-Prem Gateway, and other settings for SSAS Live Connection; Everything was fine before Gateway's latest update, but now when refreshing report on powerbi website or interactive with visuals (like checking a filter), all visuals go X and I receive this error:

We reached the data gateway, but the gateway can't access the on-premises data source.
Please try again later or contact support. If you contact support, please provide these details.

Hi @behnam_ab,

When adding SSAS data source under gateway, does the Windows account you enter have server administrator permission for the SSAS instance?

Besides, what account do you configure  to run SSAS Service? Do you use alias or actual server name to connect to the SSAS server?

Thanks,
