Now I get NUGET error  
UATHelper: Packaging (Windows): D:\Epic Games\UE\_5.5\Engine\Source\Programs\Shared\EpicGames.IoHash\EpicGames.IoHash.csproj(0,0): error NU1301: Unable to load the service index for source [https://api.nuget.org/v3/index.json](https://api.nuget.org/v3/index.json). (D:\Unreal Projects\CitySample\Build\Scripts\CitySample.Automation.csproj)

Did you managed to package UE5.5 Matrix city demo?  
How long did it took on your CPU?  
I’ve researched NUGET error on the Inet, but didn’t find any working solution. Any ideas? =)
