Resolver IIUpdate connection with Sharepoint: 'the underlying connection was closed'
I am having a serious problem in which I am unable to access any connections made by PowerQuery and Sharepoint files. It keeps showing the message 'the underlying connection was closed, it was not possible to establish a trust relationship'.
Can someone help me?

If it is everything, you should contact your IT SharePoint admin. There could be a service issue, or they made a change to permissions across the tenant that is impacting your connection.
I assume when you type in your login credentials on Office.com it works, but not here, right?
PietroFariasLogin to Office.com, works perfectly. I manage the administrative center of the organization and have not made any changes. The only time this error appears is here, in Power Query.
