Inside a windows docker container, SSL verification fails for some but not all hosts. 

See this issue over in the docker repo:
https://github.com/docker-library/python/issues/359

Maybe you guys could shed some light on what could be the possible.

To reproduce, install Docker for Windows and then:

This works:
```
docker run -ti python:3.7-windowsservercore-1809 python -c "import urllib.request as r; r.urlopen('https://bootstrap.pypa.io').close()"
```

This doesn't
```
docker run -ti python:3.7-windowsservercore-1809 python -c "import urllib.request as r; r.urlopen('https://google.com').close()"
