Cloudflare tunnel

A Cloudflare tunnel gives your server a public address through Cloudflare's network, without opening ports on your router. In Settings → Remote Access, set the Direct connection method to Cloudflare, then pick a variant:

• Quick Tunnel. A temporary address with no Cloudflare account needed. Good for a quick test. The address changes each time.
• Named Tunnel (Token). Use your own domain. Create a tunnel in your Cloudflare dashboard and give it a public hostname that points at your server, for example https://192.168.1.10:3443. The server uses a self-signed certificate, so turn on No TLS Verify in the tunnel's origin settings. Then paste Hostname and Tunnel Token here. Your domain must already be a zone in your Cloudflare account.
• Named Tunnel (OAuth). Use your own domain, with camera.ui doing the setup. Enter a hostname, choose Connect Cloudflare, sign in to authorise your zone, and camera.ui creates the tunnel and DNS record for you.

With cloud access on, camera.ui keeps a public address up at all times. If your named tunnel stops connecting, it starts a Quick Tunnel so the server stays reachable and tries your tunnel again about every ten minutes. Each failed retry leaves you on a new Quick Tunnel address, and the apps need a moment to find the server again.
