There is no error shown. Can you show it?
OneDrive failing : “The remote server returned an error: (410) Gone.” describes what could happen if Duplicati prior to the current 2.0.5.1 Beta was used, and you chose Microsoft OneDrive instead of Microsoft OneDrive v2. What Duplicati are you on (see About → System info if you want to look)?
Personal OneDrive should be easy. Pick v2 and not the MS-discontinued original, removed in 2.0.5.1.
There is no such signup AFAIK. It’s Duplicati termonology. Do you have a link to where you signed up?
EDIT: To clarify, Microsoft has only one OneDrive, but they’ve had two different ways to get to the files.
Migrating from Live SDK to Microsoft Graph explains their move to Graph, which Duplicati may call v2.
