Nginx Reverse Proxy

This example proxies your-domain.com to a Komari server running on 127.0.0.1:25774.

server {
    listen 80;
    server_name your-domain.com;

    location / {
        proxy_pass http://127.0.0.1:25774;
        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;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";

        proxy_buffering off;
        client_max_body_size 50M;
    }
}

Important Settings

• proxy_http_version 1.1 is required for WebSocket.
• Upgrade and Connection headers allow WebSocket upgrades.
• proxy_buffering off helps with real-time behavior.
• client_max_body_size 50M allows larger uploads.

Reload Nginx after editing:

sudo nginx -s reload

WebSocket Troubleshooting

Starting with Komari 1.0.8, the built-in theme can fall back to POST requests for most features when WebSocket is unavailable. The terminal still requires WebSocket. Some third-party themes may also require WebSocket.

If WebSocket fails, check the proxy config and the WebSocket Origin settings in the Komari admin dashboard.
