Refresh Token Expired

Hi all,


we have several datasets in PBI workspace connected to same Azure Analysis Service server, using OAuth2 authentication and Organizational Privacy level.


all datasets have scheduled refresh, but 2 of them are constantly getting "Refresh Token Expired" error:



When going to the defined credentials, all looks good and there are no undefined data sources or undefined credentials:



Editing the credentials and signing in again resolves the issue, sometimes for an hour - sometime for days.

IT claims the user has no predefined expiration and is not supposed to expire after a set period of time.


And again - the same exact settings work for some datasets with no problems.

This is a PBI reliability issue that really hurts our credibility as BI department and drastically reduces our uptime. We don't even get notifications ourselves that datasets are not refreshed that way.


Any assistance would be helpful!

Hi All, Did anyone find a solution for this. We have a dataflow that was refreshing fine for a couple weeks and all of a sudden this started and it fails every single day. I've tried re-entering credentials and creating a new dataflow by copying the scripts, but it doesn't work. Seems Microsoft changes things behind the scenes and things mysteriously stop working.

Hi @YOV ,


It sounds like it wants you to reenter credentials. Please make sure that you are granted permissions with all data sources. You could delete the connections and re-connect to have a try again.


Or go to .This forces an update of your credentials.


Otherwise, You could check the Issues forum here:

Thanks @v-eqin-msft .
However reentering credentials solves the issue for a day or two and then the error persists.
Forcing and update on credentials changed nothing.

We have a priority A ticket with MS support, already escelated to MS DEV team. Looks like a problem with PBI.


I also have same problem. Did Microsoft solve the issue?




Not to the best of my knowledge.

We opened a ticket for MS support, and after about a month of back-and-forth with different support tiers we gave up.

One month after that it resumed working as if nothing happened.


We're having the same problem day after day.

We've also opened a ticket for MS support, but we haven't had a solution yet.

Have you had one?



Hello, Please did you find a solution to this?

I am getting the same error. Did you find any solution from Microsoft or how did you solve it.

I am also having the same problem.

We are also having this issue for all dataflows that are connected to an on-prem data gateway. For stand alone dataflows (i.e. not configured in an on-prem data gateway) we don't have any issues with expiring oauth tokens - so for us this is specifically related to any reports that we combine an on-prem data source together with a dataflow in the PBI service.


Did anyone ever get a resolution around this from MS?
