Reverse Proxy (Nginx)

server {
    listen 443 ssl;
    server_name plex.yourdomain.com;

    ssl_certificate /etc/letsencrypt/live/plex.yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/plex.yourdomain.com/privkey.pem;

    location / {
        proxy_pass http://localhost:32400;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # WebSocket
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
