Hello,

Earlier we had facing an issue with AI Sync, AIUpdateSvc logs contains below error

Authentication: Did not find machine certificate in ALM store
Enrollment Certicate Path is
Redirected to URL https://sc.microsoft.com/CatalogService/service.svc
WebException trying to enroll: Status = ProtocolError
Exception attempting sync - The request failed with HTTP status 403: Forbidden.

we found the below blog and followed accordingly

In next sync, catalog download was success,but in the below messages we see "Authentication: Did not find machine certificate in ALM store", is this an error or warning message and how to rectify this?

Yes, I know this is an old post, but Im trying to clean them up. Did you solve this problem, if so what was the solution?

Since no one has answer this post, I recommend opening a support case with Microsoft Customer Support Services (CSS) as they can work with you to solve this problem.
