Since a few days, I have problems on all my websites (Wordpress and Joomla) with postprocessing to Upload OneDrive Personal.
The backup it selves goes well. but postprocessing fails.
Also the " transferring archive" options fails.
I get the following error:
Uploading the backup archive failed.Akeeba\Engine\Postproc\Onedrive::multipartUpload - Maximum number of retries exceeded.
The upload has failed.
Error unauthenticated: Unauthenticated
Manually login to OneDrive works.
I tried to re-authenticate, but this doesn't help.
What did help was changing the postprocessing setting to OneDrive LEGACY.
After re-authenticating, uploading to OneDrive worked again.
I don't know if something was changed here?
Or maybe something is changed on Microsoft side?
For now I have a workaround. But I don't know what caused this...
