| title: Reverse-proxy
 | |
| ---
 | |
| 
 | |
| :::info
 | |
| Since authentik uses WebSockets to communicate with Outposts, it does not support HTTP/1.0 reverse-proxies. The HTTP/1.0 specification does not officially support WebSockets or protocol upgrades, though some clients may allow it.
 | |
| :::
 | |
| 
 | |
| If you want to access authentik behind a reverse-proxy, there are a few headers that must be passed upstream:
 | |
| 
 | |
| -   `X-Forwarded-Proto`: Tells authentik and Proxy Providers if they are being served over a HTTPS connection.
 | |
| -   `X-Forwarded-For`: Without this, authentik will not know the IP addresses of clients.
 | |
| -   `Host`: Required for various security checks, WebSocket handshake, and Outpost and Proxy Provider communication.
 | |
| -   `Connection: Upgrade` and `Upgrade: WebSocket`: Required to upgrade protocols for requests to the WebSocket endpoints under HTTP/1.1.
 | |
| 
 | |
| It is also recommended to use a [modern TLS configuration](https://ssl-config.mozilla.org/) and disable SSL/TLS protocols older than TLS 1.3.
 | |
| 
 | |
| The following nginx configuration can be used as a starting point for your own configuration.
 | |
| 
 | |
| ```
 | |
| # Upstream where your authentik server is hosted.
 | |
| upstream authentik {
 | |
|     server <hostname of your authentik server>:9443;
 | |
|     # Improve performance by keeping some connections alive.
 | |
|     keepalive 10;
 | |
| }
 | |
| 
 | |
| # Upgrade WebSocket if requested, otherwise use keepalive
 | |
| map $http_upgrade $connection_upgrade_keepalive {
 | |
|     default upgrade;
 | |
|     ''      '';
 | |
| }
 | |
| 
 | |
| server {
 | |
|     # HTTP server config
 | |
|     listen 80;
 | |
|     listen [::]:80;
 | |
|     server_name sso.domain.tld;
 | |
|     # 301 redirect to HTTPS
 | |
|     return 301 https://$host$request_uri;
 | |
| }
 | |
| server {
 | |
|     # HTTPS server config
 | |
|     listen 443 ssl http2;
 | |
|     listen [::]:443 ssl http2;
 | |
|     server_name sso.domain.tld;
 | |
| 
 | |
|     # TLS certificates
 | |
|     ssl_certificate /etc/letsencrypt/live/domain.tld/fullchain.pem;
 | |
|     ssl_certificate_key /etc/letsencrypt/live/domain.tld/privkey.pem;
 | |
|     add_header Strict-Transport-Security "max-age=63072000" always;
 | |
| 
 | |
|     # Proxy site
 | |
|     location / {
 | |
|         proxy_pass https://authentik;
 | |
|         proxy_http_version 1.1;
 | |
|         proxy_set_header X-Forwarded-Proto $scheme;
 | |
|         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 | |
|         proxy_set_header Host $host;
 | |
|         proxy_set_header Upgrade $http_upgrade;
 | |
|         proxy_set_header Connection $connection_upgrade_keepalive;
 | |
|     }
 | |
| }
