[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] SSL plugin might fail on Windows 7 (#236)

[CyrilFerlicot]

If I execute this code:

```Smalltalk
ZnClient new url: 'https://google.com'; get.
```

I get a result.

If I execute this code:

```Smalltalk
ZnClient new url: 'https://github.com'; get.
```

I get this error: Error: SSL Exception: connect failed [code:-5]

I tried with both stable and latest vm. (The stable is from august 2017 I think)

I sent a mail on the Pharo dev ML and we are at least two having this problem with Windows 7 when it's working with Windows 10.

Here are the details and the stack:
