Credential issues in Power BI connecting to SharePoint based excel spreadsheet

[Anonymous]

Hello,

I've tried connecting to SharePoint as a data source from a SharePoint folder and also from the web as highlighted from the video tutorial here 

Whenever I try to connect a datasource from SharePoint I receive this notfication: 

I've tried all sorts of things to try and bypass this. I found a solution at a certain point but then after I reloaded the data on another day, it got disconnected and I began receivng this notification again.

I have the same credential issue.  It happened when I tried to setup refresh schedules in the semantic model in Power BI Service.

My Excel file is in a folder in a Microsoft Teams. 
I used Power BI Desktop to import the data from the file.  It did not ask me my credential.  

Published it to a workspace was fine.

It was at the semantic model schedule mentioned earlier that I encountered the credential problem.

I thought perhaps I needed to use a data gateway connection instead.  When I tried to create a connection, I encountered the same credential error.

If anyone is struggling with this same issue, I ended up figuring out a solution from within Power BI desktop:

1. Going to File > Options and settings > Options.

2. Under the GLOBAL menu, going to Security, and scrolling down to Authentication Brower and check the box for Use my default web browser.

Then I refreshed my data and was able to connect SharePoint as a data source.

Clear permission in data source setting

[Anonymous]

Hello @amitchandak ,

Thanks for reaching out!

I am unable to connect the data source to Power BI, so there are no data source files to clear permissions. Would I clear permissions from SharePoint?

Here is some additional background info, if it is helpful...

So I am trying to access a dataset from shared SharePoint folder were I was granted permission to edit. I'm not sure if I need special permissions to connect to Power BI, or how to access that option, if it exists.

To test this I created my own SharePoint page, folder, and then a test excel spread sheet. On this page I am the "owner" but when I attempted to connect the test excel spreadsheet to Power BI I received the same "We're unable to connect. Please delete your credentials and try again later" notification. Am I missing something?

Hello again @amitchandak ,

A quick follow-up,

There was another case I had last week and was experiencing the same issues. I was able to connect a data source from SharePoint to Power BI. It was refreshing the data and I had no problems. However, the next day, everything changed. I was unable to refresh the data an ran into the same error, "We're unable to connect. Please delete your credentials and try again later"

I just revisited this case to try and clear the permissions in the data source setting, nothing seems to happen:

And when I try to specify my credentials I receive this notification:

Any help at all would be much appreciated!
