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.
|
|
|
|
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;
|
|
'' '';
|
|
}
|
|
|
|

|
location / {
|
|
return 301 https://$host$request_uri;
