We do not support sending SOCKS5 requests directly to the proxy zones, but in our Proxy Manager, every port that is created listens by default to HTTP/HTTPS and SOCKS5.
See an example of SOCKS5 request using curl on port 24000:
curl -x socks5h://localhost:24000 http://lumtest.com/myip.json
The same 24000 port can be used for HTTP like this:
curl --proxy localhost:24000 http://lumtest.com/myip.json
