I tried the ini fix, changing the values to very high numbers:
[HTTP]
HttpTimeout=36000
HttpConnectionTimeout=20000
HttpReceiveTimeout=20000
HttpSendTimeout=20000
and my download continues to hang at 2% (2.75 GB remaining). After a couple hours of 0.0 B/s I get the error “Could not download patch data. Please try again later.” Logs are attached (the “UnrealEngineLauncher.log” isn’t finished so it stops suddenly, but the most recent backup has a full download attempt and the patch data error). The others are cancelled after a while of 0.0 B/s (and many are from before I tried the fix in this post).
I’ll have faster Internet in about a week but I’d really like to get my hands on UE4 as soon as possible. Might just do some UT3 mapping if I have to wait.
