So, I did download the UE4 Source code by ZIP Download. At first, it seems to download normal as usual, but at some point (I believe at around 125MB), it stops and says “Download failed” (I use Firefox). Is this a GitHub related issue?
No, GitHub works normal, it looks like you have unstable connection, like mobile 3G or WiFI interference somewhere.
I have a copy the latest stable (4.23.0) branch from GitHub, with nothing changed inside.
If you have troubles with downloading from github, i can send you a link to my cloud with this zip.
P.S. It’s around 353 Mb.
