Unable to connect to One Drive for Business: Error from token exchange: Bad authorization header scheme


Quite an annoying issue. Occured when working with flows and power automate. 

A connection using OFB to an excel table wasn't working, getting the 'Error from token exchange: Bad authorization header scheme' error, so I decided to disconnect and restablish said connection. Now I can't even connect to OFB (making a new connection, or using an old connection to find the file).


Without connection to OFB, my applications are no longer populating my galleries.
