Hi jeferson,
Hmm, this sounds like a problem with either the connection to our servers, or the connection to the cloud storage we use. The best way to diagnose this further is to enable very verbose http logging. Can you edit Engine.ini in the following directory:
c:\Users\YOUR_USER_NAME\AppData\Local\UnrealEngineLauncher\Saved\Config\Windows\
and add the following lines:
[Core.Log]
LogHttp=veryverbose
LogOnline=veryverbose
Try running the launcher again to reproduce the problem, then shut down the launcher and post your latest log from:
c:\Users\YOUR_USER_NAME\AppData\Local\UnrealEngineLauncher\Saved\Logs\
We should be able to diagnose things further from there. Thanks!
Carlos
