Hi,

I am trying to onboard an ATP client on Windows 10 using SCCM.

SCCM states the policy was applied correctly. The ATP service is running, the sense logs only contains warning and error messages stating the following:

Contacted server 20 times, failed 14 times and succeeded 6 times. URI: https://winatp-gw-neu.microsoft.com/. Last HTTP error code: 400

 

The ATP connectivity verifier states the client is onboarded along with HTTP code 200 success messages.

Any ideas what to check?

I think you are looking for the Microsoft Defender ATP community, which can be found here - https://techcommunity.microsoft.com/t5/Microsoft-Defender-ATP/bd-p/MicrosoftDefenderATP
