These components act as gatekeepers, controlling inbound and outbound traffic, but misconfigurations can unintentionally block legitimate update requests.
Firewalls are designed to protect systems from unauthorized access by filtering traffic based on predetermined security rules. However, overly restrictive firewall settings can prevent Windows Update from communicating with Microsoft’s servers. For instance, if outbound connections on specific ports (such as TCP port 80 or 443) are blocked, update requests will fail, resulting in Error 0x80072EFD.
Similarly, proxy servers—commonly used in corporate environments to monitor and control internet access—may interfere with update traffic. Incorrect proxy settings or authentication failures can obstruct Windows Update’s ability to reach external servers. In some cases, the system might be configured to use a proxy that no longer exists or requires credentials that have changed.
It is also important to consider that some security software includes built-in firewalls or web filtering features that act like proxies. These can introduce additional layers of complexity, making it harder for Windows Update to establish a direct, trusted connection.
