Save and close the file. Restart the PHP-FPM service to apply your updates: sudo systemctl restart php8.x-fpm Use code with caution. Step 5: Download and Extract Nextcloud

Even with careful planning, HaRP installations can hit snags. Here are the most frequent issues and how to resolve them:
The easiest way to start is using the official nextcloud/HaRP GitHub image. You'll need to define a shared key for secure communication.
If you want to access your music collection outside your home network, you must secure the installation. harp nextcloud install
Add a custom PHP configuration file: .harp/overrides/php.ini
"apps": "collabora": "enabled": true, "domain": "office.yourdomain.com"
The Nginx web server user ( www-data ) must own the Nextcloud directories to read, write, and execute files seamlessly.
Harp will:
Harp will need ports 22 (SSH), 80 (HTTP), and 443 (HTTPS) open.
To enable direct routing (and WebSockets), your main reverse proxy (Nginx, Apache, or Caddy) needs a redirect for the /exapps/ path.
: Requests to https://your-domain.com should be forwarded to the HaRP container's internal IP at port 8780 .
Setting Up HaRP for Nextcloud 32+ (High-performance AppAPI Reverse Proxy) is the new recommended bridge for running External Apps (ExApps) in Nextcloud 32 and beyond. It replaces the older DockerSocketProxy, offering better performance and native support for features like WebSockets . Why Use HaRP? Save and close the file
Upload a 2GB file via the web interface. Because Harp configured Nginx client max body size and PHP post max size, this should work immediately. If you are behind a reverse proxy (Cloudflare), you may need to tweak, but Harp's default Nginx template handles it.

: Some users have reported issues with older Docker versions; ensure you are running a recent version (v29+ is recommended) to avoid API client mismatches.
Remove your existing ExApps (do delete their data volumes) and reinstall them; they will now deploy via HaRP. Safely remove the old DSP container. Troubleshooting Common Issues AppAPI and External Apps - Nextcloud Documentation Fix: Run this on the server: Even with
