paket push inside container fails with 500 InternalServerError, System.IO.IOException

[peterhirn]

paket push works on windows clients but fails inside a alpine container.

container:

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-alpine3.9 as dotnet

ENV DOTNET_CLI_TELEMETRY_OPTOUT=1
ENV PATH="/root/.dotnet/tools:${PATH}"

RUN dotnet tool install paket -g

dotnet nuget push works:
dotnet nuget push -s http://workstation11:5000 -k 185f3958-cdb8-4fb3-aca9-b6af9fe40862 test.nupkg

paket push fails:
paket push --url http://workstation11:5000 --api-key 185f3958-cdb8-4fb3-aca9-b6af9fe40862 test.nupkg

liget exception:
