SharePoint - Error 'DNS_PROBE_FINISHED_NXDOMAIN' when accessing SharePoint or OneDrive

Symptom

Cause

Your subscription to either SharePoint or OneDrive might have expired.

Resolution

Reactivate your subscription

To reactivate your Microsoft 365 subscription, see Reactive your subscription

Flush the DNS cache

If your subscription is active and you are still facing the issue, that could be a backlog in the local systems DNS cache which can be removed.

To flush the local systems DNS cache:

1. Select the Start button.

2. Type cmd and open the Command Prompt app.

3. In the Command Prompt window, enter the command ipconfig /flushdns.

4. Select Enter on the keyboard.

Once the DNS has been flushed, try to access SharePoint or OneDrive again.

If you are still unable to access your service, contact Microsoft technical support.
