Scheduled Cache Refresh Azure Analysis Services fails

[Strizzolo]

Hi,

I have a problem regarding Azure AS connection. I have a report live connected to a Tabular model inside Azure AS, published on the service.

Microsoft credentials used on the data source settings are correct. Manual refreshes work fine.

The problem is about scheduled cache refreshes: after 8 hours, Power BI sends me this error: "It looks like the refresh token expired. Please go to this dataset's setting page, and reenter the undefined credentials for the undefined data source." and disables the scheduled refresh. Manual refreshes still work fine. Every time I successfully reenter my credentials, after 8 hour this problem reappears.

Am I doing something wrong?

Thanks.

Unfortunately that was not the reason for the error, however it resolved itself. We didn't find out why. Thank you anyway!

Hi there

I would chat with your network admin.

It appears that your account expires after 8 hours causing the token to fail.

The best solution is to have an account which has got access to your AAS Server and where the account token does not expire after a certain amount of hours>?

Hi Gilbert

thanks for the answer.

I am ignorant: can an account expire after only 8 hours? And every time I schedule the cache refresh?

Thanks.

As far as I know the network Admin in Azure Active Directory can specify how long a login token is valid for.

I think 8 hours is how long people typically work for, so this might be a coincidence?
