Error on HTTP tracker announce request after updating the demo

[josecelano]

I have updated the demo and I'm getting this error trying to make an HTTP announce request:

$ cargo run --bin http_tracker_client announce http://tracker.torrust-demo.com:7070 9c38422213e30bff212b30c360d26f9a02136422

The problem was I was making the request directly to the tracker container:

http://tracker.torrust-demo.com:7070

Instead of using the proxy (nginx):

https://tracker.torrust-demo.com

The error was OK; the tracker configuration enabled the reverse proxy with:

[core.net]
on_reverse_proxy = true

However, the request does not contain the X-Forwarded-For header since we are not using the proxy for the request.
