Can´t configure gateway with analysis service

[guibenassi]

I can´t configure sucessfuly the gateway to use with Analysis Service.

I did it before, but stop working and I don´t know what happens.

I have an Analysis Service Cube, I can refresh it normally.

In the power Bi desktop it works fine.

When I try to use the service the gateway give an error, I am posting the gateway log error above:

Hi @guibenassi 

Can you make sure that you have got the latest version of the MSOLAP installed?

And also make sure that the user account you are using to connect has Admin permissions on your SSAS Server?

Hello @GilbertQ 
Thank you for your comments.
I updated the latest version of MSOLAP, and I check the admin permission, everything looks fine.

But I still get the error.

Hi @guibenassi 

When configuring the data source in the Power BI Service, can you use an Admin account on your SSAS Server?
