Hello Duplicati team,
I’ve been using Duplicate for backing up my Windows 10 PC to Onedrive for years now, and it was working great, thank you so much for this great software!
A few days ago, without any changes on the Duplicati side (and without any other changes I’m aware of), backups stopped working though. Basically any task that would require some network connectivity (backup, restore, verify) fails with “A task was canceled”.
Here is a log entry I got from a verify attempt (backup and restore fail with the same TaskCanceledException):
{“ClassName”:“System.Threading.Tasks.TaskCanceledException”,“Message”:“A task was canceled.”,“Data”:null,“InnerException”:null,“HelpURL”:null,“StackTraceString”:" at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n at Duplicati.Library.Backend.MicrosoftGraphBackend.SendRequest[T](HttpRequestMessage request)\r\n at Duplicati.Library.Backend.MicrosoftGraphBackend.SendRequest[T](HttpMethod method, String url)\r\n at Duplicati.Library.Backend.MicrosoftGraphBackend.d__69

I tried updating 2.0.6.1, as well as re-installing Duplicati - both ran fine, but the problem remains. I’m not sure why, or how I could troubleshoot this further - can you give any hints?
I can provide further logs if needed (if you tell me where from).
Thank you very much in advance!
