How to use Onhape trought proxy?

I'm trying to access my work through an http proxy. Initial home page loads fine, but the actual project workspace won't load.I'm suspecting that onshape uses a port for communication with it's servers, that is caught on the firewall. What port exceptions do I need to get from the sys admin? - or is it a totally unrelated problem?

Mozilla Firefox 55.0.2 Ubuntu 16.04
proxy open ports:
PORT STATE SERVICE
53/tcp open domain
80/tcp open http
3128/tcp open squid-http
8080/tcp open http-proxy
Thanks in advance!

Hi @ffoska_foska. Your proxy needs to support WebSockets. We do all of our communication over port 443, but if your proxy can't handle WebSockets, you won't be able to model.
