Which server is the Unreal Launcher connecting to?

I am asking because my Windows host file was blocking that server and I was unable to logon to Launcher until I disabled my host file (which has over 80,000 hosts).

I would like to know which server it connects to so I can remove it from my host file.


EDIT: Well the IP it’s connecting to I think belongs to Amazon CloudFront? I have that blocked in hosts. But I need confirmation on servers just to be clear.

OK, so the host Unreal Launcher connects to is “cloudfront-labs.amazonaws.com”. If your launcher isn’t connecting and you are using custom host files, make sure this host isn’t being blocked there.

I tried other methods listed on Unreal site for fixing Launcher network issues but they were useless. This was the thing causing the problem in the end.
