OneDrive download item not working

[E3Solutions]

Trying to download a file. This sample code has been working, now all of the sudden it is throwing an error:

using (var stream = await this.oneDriveClient.Drive.Items[item.Id].Content.Request().GetAsync())
using (var outputStream = new System.IO.FileStream(dialog.FileName, System.IO.FileMode.Create))
{
await stream.CopyToAsync(outputStream);
}

Error:
Exception of type 'Microsoft.Graph.ServiceException' was thrown.
Error Code: itemNotFound

This has sort of been up and down today (12/8/16). It has been working randomly, but most of the time down.

Please advise.

We have the same problem using the C#/.NET SDK with ItemNotFound error and 'Microsoft.Graph.ServiceException'. This started after MS did an update to OneDrive on 12/7. We opened a support ticket with O365/OneDrive team. They said they are not aware of any issues from rollout and said we needed to contact API support. The weird thing is it works sometimes, maybe 2 out of 100 tries. Listing files and uploading still work but downloads fail.

Here's what we have tried so far:
•Latest sample project from GitHub, same error
•Check settings in SharePoint for new settings that may affect this,none found
•Re-register the App in Azure AD
•Increased app permissions in Azure AD
. Variations in Content Request Code

The line of code that fails is:

var stream = await this.oneDriveClient.Drive.Items[item.Id].Content.Request().GetAsync();
