2]Manage connection endpoints

Primarily intended for IT or system administrators, that aspect of troubleshooting where your Windows device cannot access Windows Update files requires you to ensure that Windows 11/10 devices can reach the necessary Windows Update endpoints through the firewall. So make sure that the required ports are open in the firewall and that the following protocols as shown in the table below should be able to reach the respective endpoints:

Protocol Endpoint URL
TLS 1.2 *.prod.do.dsp.mp.microsoft.com
HTTP emdl.ws.microsoft.com
HTTP *.dl.delivery.mp.microsoft.com
HTTP *.windowsupdate.com
HTTPS *.delivery.mp.microsoft.com
TLS 1.2 *.update.microsoft.com
TLS 1.2 tsfe.trafficshaping.dsp.mp.microsoft.com

The caveat here is to make sure you don’t use HTTPS for endpoints that specify HTTP, and vice versa; otherwise the connection will fail. Keep in mind that the specific endpoints may vary between Windows client versions.

For more details on how you can manage connection endpoints for Windows 11/10 devices, see this Microsoft documentation.
