Very slow RUN on docker on windows containers

Question

I installed docker on a Windows 10 machine via chocolatey choco install docker-desktop

Then I have built this image

FROM mcr.microsoft.com/windows/servercore:ltsc2016
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop';"]

RUN Invoke-WebRequest -UseBasicParsing https://chocolatey.org/install.ps1 | Invoke-Expression

And it runs reasonably fast

Then I try to run this one

FROM chocolatey
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop';"]

RUN cinst -y netfx-4.7.2-devpack

After downloading the .net installer the process fails with timeout. The last thing in the log is Installing dotnetfx...

No idea why and how to debug. Anyone has the same issue? Where do I start debugging this issue?
