I configured an Apache2 on Ubuntu Server 16.04 as an http reverse proxy to an external web server.



There's something very curious here, as pages are loaded, some of its resources (.css, .js) return 404, not all the time, but randomly.



To try to figure out what's happening I checked with cURL from inside this server using curl -v -k "https://127.0.0.1:444/proxyed_path/css/resource.css" and found as I already knew sometimes I got correct results but when I execute this command repeatedly I get the google 404 error.



This is the error I'm getting:
