Proxy server access possible?

Hi,

I would like to access the Epic Game Launcher and data from an internal server in the Unreal Engine. So far, no traffic from Unreal is detected on the proxy server and help has not provided a solution.

There are old entries from more than 5 years ago in which it is written that a proxy implementation is being worked on. So something should have happened in all those years.

Many thanks in advance.
