unable to use in virtualbox

I want to use mkcert generated certificates into the ubuntu virtual machine inside the VirtualBox.

I try but no success

**Chrome(on Windows 10) Error:** windows does not have enough information to verify certificates

note - I installed mkcert using choco in windows 10 and generate certificates and then import them into vm.

Host: Windows 10
guest: ubuntu 18.04 Linux virtual machine in VirtualBox.
