Data source credentials are missing or invalid - Folder SharePoint

[Syndicate_Admin]

Hi colleagues,

For months now, I have created some data flows (5 different flows) in PowerQuery within PowerApps.
The thing is that I have been getting this error in all flows for a few days now and I can't find the error.

Challenge Error, Error details: Data source credentials are missing or invalid. Please update the connection credentials in settings, and try again.

Hello, thanks for the answer. But the error appears before I can create the flow.
I show an image with what happens to me:
I have entered the PowerPlatform Administration Center and deleted all connections to make them again, but the problem persists.

The error message is:
Unable to create an OAuth connection. Reason: "Unexpected error (Session ID: 41b51afb-ab90-417c-bef2-26ca44721afb, Region: europe)."
