Why can I not upload files on OneDrive App?

[WPCentral Question]

I have a WP8.1 Nokia Lumia 625. My OneDrive app has the latest update. I have files on OneDrive and am able to open them and edit them in Office Hub. However when I try to save these changes, it says 'couldn't upload'. I am connected to wifi and my other devices are able to upload files quickly on OneDrive.

When I view the status, it says 'We don't support this authentication scheme. Contact the person who manages this SharePoint site.'

My OneDrive app used to work... but not anymore.

Reinstall your OneDrive app, and reconnect your Microsoft Account. Reset Office (settings>applications>Office). Then, do a reboot or a soft reset.

That'll most likely solve your problem.

I used to have this problem before, couldn't upload edited docs. You mentioned viewing status, you can try again to upload directly from there.
I think this happens if you have VERY slow internet connection (I do at my work).

@Wandering you can't reinstall OneDrive anymore. Its system app now
