Hi @Janne Kujanpää ,
Please access Defender for Endpoint to ensure that the machine was successfully onboarded. You can check the Event IDs and error codes listed in the linked article to ensure that there were no errors in the onboarding process.
Note also that if you enabled the fix recently, it can take up to 48 hours for the changes to reflect in the vulnerabilty scan. See: FAQ
If Defender for Endpoint does not show onboarding errors and you have gone past the 48 hour mark but are still seeing this issue, feel free to reach out to me at AzCommunity@microsoft.com ("Attn: Marilee Turscak"), include a link to this thread, and your subscription ID, and I can get a one-time free support case opened for you.
If the information helped you, please Accept the answer. This will help us as well as others in the community who may be researching similar issues.
