How to Configure SCCM Management Point for HTTPS | ConfigMgr

Microsoft deprecated HTTP-only communication in Configuration Manager to increase security. The HTTP-only communication will not be supported with first release after Oct 31, 2022. Hence, existing infrastructure should be configured for HTTPS based communication in ConfigMgr.

The HTTPS communication can be enabled using PKI certificates. The HTTPS communication is also required for Management Point if you want to use Cloud Management Gateway (CMG) to support internet-based clients. If you are not ready for HTTPS based communication for all clients and need HTTPS management point for CMG only then dedicate a SCCM management point for CMG and configure that one for HTTPS.

In this blog post, we will walk through the SSL requirements and configuration for SCCM management point. We will use SSL certificates from Microsoft Public Key Infrastructure (PKI)
