Explanation
BranchCache Distributed Cache mode allows client computers to act as local peer caches, sharing cached content with other clients on the same subnet using peer-to-peer communication. This peer traffic uses specific ports (TCP 80 and the WS-Discovery port 3702) that are blocked by Windows Firewall by default. While the GPO enables BranchCache, you must separately configure Windows Firewall inbound traffic rules on the clients to allow BranchCache peer-to-peer traffic. Without these firewall rules, clients cannot communicate with each other to share cached content. BITS handles background downloads, Offline Files manages offline document access, and Advanced sharing settings control network discovery - none of these enable the required BranchCache peer communication.
