Vaultwarden/PROXY.md

Proxy examples

In this document, <SERVER> refers to the IP or domain where bitwarden_rs is accessible from. If both the proxy and bitwarden_rs are running in the same system, simply use localhost. The ports proxied by default are 80 for the web server and 3012 for the WebSocket server. The proxies are configured to listen in port 443 with HTTPS enabled, which is recommended.

When using a proxy, it's preferrable to configure HTTPS at the proxy level and not at the application level, this way the WebSockets connection is also secured.

Caddy

localhost:443 {
    # The negotiation endpoint is also proxied to Rocket
    proxy /notifications/hub/negotiate <SERVER>:80 {
        transparent
    }
    
    # Notifications redirected to the websockets server
    proxy /notifications/hub <SERVER>:3012 {
        websocket
    }
    
    # Proxy the Root directory to Rocket
    proxy / <SERVER>:80 {
        transparent
    }

    tls ${SSLCERTIFICATE} ${SSLKEY}
}
