- Switch all CLI examples to Docker Compose V2 (docker compose) for consistency.
- Add explicit instruction to grant write permissions to the host logs/ directory (chmod 777 -R logs) to fix coturn/nginx bind-mount logging errors.
- Parameterize TURN UDP port range via TURN_MIN_PORT/TURN_MAX_PORT and set a safer default 49152-49252 to reduce startup/cleanup overhead and port
conflicts.
- Update troubleshooting with coturn log write failure guidance and port conflict hints.
- Clarify that LAN IP is auto-detected in private mode; --local-ip is no longer needed by default but remains as an override for edge cases.
nginx(website on server) listens on port 4443 and then forwards to the frontend and backend.
nginx main configuration adds a stream block to uniformly listen on port 443, then forwards based on domain to coturn(5349) and website(4443).
The TURN port used in WebRTC is changed to 443.
The deployment document adds a script action to delete extra configurations generated by certbot.
