Details
While the most common reason for this error is a mistake in username and password, there could be other reasons for the connection failure.
When the connection fails between the migration tool and your environment, the migration tool does not receive precise information from SharePoint or Microsoft 365 about the error.
The migration tool cannot provide a precise cause.
If your username and password are correct, you can validate other potential causes to find a solution.
