Splunk Cloud Platform

O365 Add-on sudden stop forwarding of logs, "Data input was interrupted by an unhandled exception." error.

Path Finder

We were successfully ingesting O365 management logs using the Splunk O365 add-on. We noticed a drop in events and a really small number of events being forwarded for a day after the drop. After that events stopped coming in completely.

This was a working inputs with logs coming in as expected. No change to a configuration was made to Splunk or O365 whatsoever.


Currently we can see the following error in Splunk each time the input is run. The error appears after the input successfully acquires the access token and calls the management API.

The same error appears for all add-on inputs (status, message, audit, sharepoint etc.)


Any idea what the problem might be?
