Connection between dataflow and Sharepoint : credentials rejected

Dear all,

I have a couple of dataflows connected to Sharepoint using my own credentials (email + password). I recently modified my password and forgot to make the same modification in dataflows, resulting naturally in refresh failures. The problem is that I can't modify my credentials anymore. 

Dataflows now manage to get access to the target folder but can't open excel files on it :

 

SharePoint.Files("https://xxxxxxxxx.com/sites/folder/", [ApiVersion = 15])  ====> success
step2{[Name = "xxxxxxxxx.xlsx", #"Folder Path" = "https://xxxxxxxxx.com/sites/folder/subfolder/"]}[Content] =====> failure


The obtained error is :
The credentials provided for the SharePoint source are invalid. 
 
But modifying the connection doesn't solve the issue.
 
Note that when I ask someone else to open the dataflow and modify the connection (using their own credentials) the dataflow succeeds in viewing data and even refreshes successfully. But as soon as I open it again the error happens. We don't seem to have a way to modify the connection permanently.

Thanks in advance for your help,

Hello,

I tried to remove the connection and create a new one but it didn't work. Maybe used credentials are stored somewhere in the Cache but I don't know how to empty it.

Hi @Zoubeyr ,

Based on my learning, consider clearing the browser cache and reconnect to SharePoint.

Besides, you can try to create new connection between Data flow and Share point.

You can also view the following documents to learn more information.
