Intune now requires HTTPS delivery for managed Win32 app content. This change primarily affects organizations that use Microsoft Connected Cache and haven't configured their cache nodes for HTTPS delivery. Clients that previously pulled content from Connected Cache can still download Intune Win32 apps, but those requests bypass the cache nodes and fall back to the content delivery network (CDN). This behavior can increase internet traffic and bandwidth usage.

For more information, see the blog post How to enable HTTPS support for Microsoft Connected Cache for Enterprise and Education.
