Dataset refresh error on Service

Hello Team,


My Power Bi dataset is not getting refreshed from yesterday. I have found out the issue is with Dataset that contains the Power Bi Dataflow (Legacy) connection sources.


It is throwing the error as "Access token has expired, resubmit with a new access token.". However, there is no issue when we go ahead with Power Bi desktop refresh.


The issue is not only with one dataset. The issue reasons are changing time to time. The same datasets were OKAY till yesterday evening GST.


Attaching the error messages for your reference.

What's the progress with this 'known issue'? It seems to be an unsolved issue for few months so far, could you please add it here so we can track its status?

     Hi, I managed to solve it!

 Despite appearing online (gateway test), it wasn't working: the problem started after I was 'forced' to change my office365 password, I edited the 2 Gateways and confirmed my credentials.






  I just clicked edit and confirmed the credentials. Then I tried refreshing the dataset and it worked.

 This must be done for each gateway that has credentials (file/folder/etc)
