While migrating from/to OneDrive or SharePoint, you noticed the following error in the logs: “Cannot contact web site ‘https://[tenant]-my.sharepoint.com/’ or the web site does not support SharePoint Online credentials. The response status code is ‘Unauthorized’. The response headers are ‘X-SharePointHealthScore=0, X-MSDAVEXT_Error=917656; Access denied. Before opening files in this location you must first browse to the web site and select the option to login automatically.”
The self-service password reset tool is activated for the admin of migration. Thus the platform cannot connect to your SharePoint site.
Contact your administartor to disable the self-service reset mode for the user. You can find more information here: https://support.office.com/en-us/article/let-users-reset-their-own-passwords-in-office-365-5bc3f460-13cc-48c0-abd6-b80bae72d04a
