With tcpdump I compared a working (without proxy) and a non-working
(with a proxy) Freepbx installations.
In the working one, I can see freepbx and mirror.freepbx.org
exchanging SYN and ACK packets before the first HTTP GET

In the non-working one,  I can see freepbx sending a SYN packet to
mirror.freepbx.org and obviously waiting for an answer that do not

So to me, the End Point Manager module do not care about any of my
proxy settings (in /etc/profile, /etc/apache2/envvars and
I took a quick look at source source but could not find anything relevant.

I think there is a specific issue within this module.
