- WireGuardManager: get_external_ip() (cached 1h), check_port_open(), get_server_config() returning public_key + detected endpoint - API: /api/wireguard/server-config returns real external IP; /api/wireguard/refresh-ip forces re-detection; /api/wireguard/peers/config now looks up peer IP + private key from registry and uses real server endpoint automatically - Fix doubled port in Endpoint (178.x:51820:51820 → 178.x:51820) - Fix Address=/32 when peer_ip already has mask - WebUI nginx: proxy /api/ and /health to cell-api (fixes localhost:3000 hardcode — UI now works from any machine) - api.js: baseURL='' so all calls go through nginx proxy - WireGuard page: show Server Endpoint card with external IP, endpoint, public key, and Refresh IP button Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
