 # Reverse Proxy
 
-Users can deploy a custom reverse proxy that forwards requests to Immich. This way, the reverse proxy can handle TLS termination, load balancing, or other advanced features. All reverse proxies between Immich and the user must forward all headers and set the `Host`, `X-Forwarded-Host`, `X-Forwarded-Proto` and `X-Forwarded-For` headers to their appropriate values. Additionally, your reverse proxy should allow for big enough uploads. By following these practices, you ensure that all custom reverse proxies are fully compatible with Immich.

+The Repair page can take a long time to load. To avoid server timeouts or errors, we recommend specifying a timeout of at least 10 minutes on your proxy server.

-**timeout:** is measured in seconds, and it is particularly useful when long operations are triggered (i.e. Repair), so the server doesn't return an error.
