Yep, ran into this too. The 'your server did not send a forwarding request to proxy' error often pops up when the proxy expects HTTPS but the server’s sending HTTP (or vice versa).
Double-check your scheme (http:// vs https://) in the proxy_pass directive. Also, tools like mitmproxy can help sniff the traffic and see where it’s breaking.
