Anything else we need to know:
URI for sending request by kubectl is wrong apparently:
I0303 02:58:14.153842 18760 round_trippers.go:419] curl -k -v -XGET -H "Accept: application/json, */*" -H "User-Agent: kubectl.exe/v1.13.4 (windows/amd64) kubernetes/c27b913" 'https://178.79.148.185:6443/Program%20Files/Git/apis/apps/v1'
Tried with version of kubectl got by link: https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-binary-using-curl

Probably it's related to git's minigw terminal may be it's not, however URI request sending to server is obviously not good. kubectl running in cmd and powershell works fine.

I think it is MSYS subsystem issue (e.g. see docker-archive/toolbox#673).

As a workaround run with:
MSYS_NO_PATHCONV=1 kubectl get --raw /apis/apps/v1
Or create an alias:
alias kubectl='MSYS_NO_PATHCONV=1 kubectl'

I'm using git bash and I've wasted hours of reinstalling and reconfiguring metric-server because everytime i try to do "kubectl get /apis/*" it's always returned "Error from server (NotFound): the server could not find the requested resource".

Glad to know the error is from the Windows system.

Here's me trying to get the api via Git Bash

and here's me using the CMD
