Salesforce Refresh

v-danhe-msft I'm still monitoring it at the moment, but I got in contact with my Salesforce admin and he "changed some settings" and I was able to refresh again and also enable auto refresh from the PBI service. All my reports are back on their schedules. I still do not understand what the exact cause was, but I was informed by Microsoft support it had something to do with the OAuth2 authentication method. After the August 2018 update is when my reports stopped working, so something in that update had some kind of impact on Salesforce. This was the error message reported from Microsoft:

So the only thing I did was inform my Salesforce admin that some other users resloved the issue by changing around some security settings within Salesforce and after he did that everything started working again. I was not told exactly what the changes were.
