Hi, i’ve been trying to build a fresh ue 5.1.1 release from source, when running the Setup.bat im facing an issue:

```auto
Checking dependencies...
Updating dependencies: 0% (0/97340)...
Failed to download 'https://cdn.unrealengine.com/dependencies/UnrealEngine-11447123-52802068b7db445d94de6cd13d574a02/00ba053f58ab8d00cf41519fd27d8059d397a4fb': InvalidDataException: The archive entry was compressed using an unsupported compression method.

```

I’ve tried several way using git, zip, url to https rather than http, adding all .net from 3.5 to lastest i’ve no more idea, does anyone know whats going on ?

Edit:  
I’ve switch to 5.2 and the dependencies are being downloaded, is the 5.1.1-release down ?

Solution for 5.1: replace corresponding file in your Unreal Engine downloaded directory with

[https://github.com/EpicGames/UnrealEngine/blob/5.1/Engine/Build/Commit.gitdeps.xml](https://github.com/EpicGames/UnrealEngine/blob/5.1/Engine/Build/Commit.gitdeps.xml)
