No System will not PXE Boot after switching Microsoft Endpoint Configuration Manager to HTTPS

Question

After I switched my site system to HTTPS, I am now unable to PXE boot on any system, VMs, Desktop computers, Laptops, nothing will work. It will just give me an error in the SMSPXE.log about the Management Point. I have no idea if this is a bug, I am pretty sure that I did configure everything correctly. But I have no idea if this is a bug in MECM or what. And yes it is on the latest version, 2203, site version is 5.0.9708.1000, if anyone knows why I am getting these errors, please let me know! I will link a screen snip to show what it's doing.

Hi,

The error code 0x80070490 means "Element not found". Per my experience, this issue may be related to the certificate.

When we have an environment with HTTPS only, every PXE-enabled DP should have two certificates: one for the DP itself and one for the client. The client must have a valid Boot images for deploying operating systems certificate for the client to communicate with the site and for the PXE OSD deployment to continue. And the PXE-enabled DP also need a certificate for Site systems that have a distribution point installed to communicate with HTTPS-enabled management point. Please help check if the certificates are ok.

For more information, please refer to:

Hope my answer could help you. Thanks for your time.

Best regards,
Simon
