The Upgrade and Connection headers are essential for WebSocket support. Without them, real-time features like collaborative editing and live notifications will not work.

Choose the or HaRP Proxy (Docker) template. Fill in the details: Host : Use localhost:8780 if HaRP is on the same machine. FRP Server Address : Typically localhost:8782 . Shared Key : Must match the HP_SHARED_KEY set in Step 1. Click Check Connection and then Register . Step 3: Configure Your Main Reverse Proxy

Nextcloud has evolved from a simple file-sharing platform into a comprehensive, self-hosted productivity suite. As the platform grows, so does the complexity of running advanced applications (External Apps or "ExApps")—like AI-powered tools, complex office suites, or specialized multimedia tools—that require more than standard PHP. Enter . Adopting HaRP is a significant upgrade for any

HaRP eliminates the need for complex, manual DockerSocketProxy configurations.

Manages user sessions. It handles transactional file locking to prevent data corruption during simultaneous syncs.
