Https Only, Download Failed 80190193 - client attempts http instead of https

Question

SCCM Https Only site ver 2006.
100 Distribution Points.
Windows 10 Build multiple builds.

When performing Task Sequence In-Place Upgrade, multiple clients stays very long by attempting talk to DP via http and naturally gets IIS 403. Cliet certificate is valid and I checked that correct cert is selected by CM client to talk to the SCCM site (by thumbprint).

Still it is mistery, why client tries to talk http to the DP.

Hi,

Thanks for posting in Microsoft MECM Q&A forum.

Please help check the LocationServices.log, ClientLocation.log and CertificateMaintenance.log to see if there is any further information. Also check whether the AD is working fine or not.

Thanks for your time.
 
Best regards,
Simon
