what is this error? ServerError_ASAuthenticationFailed

[ele]

why can't I find anything about this error and how do I fix it?
Seems like it's saying analysis services authentication failed. Any ideas what I need to do? These reports are using analysis services.

Apparently a known issue impacting only one client out of 8 for me. It looked isolated. I spent  a considerable amount of hours trying to get client's data back up that day. Never saw anything from MS.
Thank you all

Where I can find details about this issue? 
My clients demand an explanation as to what caused the lack of access to the data.

I had the same problem yesterday, in addition, guest users were getting an error:

would suggest to reach out to the AAS team to check the failure logs within the AAS server to get the exact cause of the scenario as the error message is too generic in Power BI service side.
