Since 7 days, cannot backup on OneDrive for Business

Hi all,
i’m using Duplicati since 2 years, with many PROS (and rare CONS).
Surprising, since 7 days, i received this message:
“Access denied. You do not have permission to perform this action or access this resource.”
No more backup is updated.

Nothing is changed and i don’t know why it happans
Can you help me?
Many Thanks.

P.S. I’m Italian, so… you’ll excuse me my english :woozy_face:

Found issue.
Microsoft OneDrive changes server access url.
Modified and solved
