Android Studio Setup Wizard (studio64.exe) is not able to fetch some XMLs.

I have set in studio64.exe.vmoptions

```
-Djava.net.preferIPv4Stack=true
-Dhttp.proxyHost=... 
-Dhttp.proxyPort=...

```

Also tried

```
-Dhttp.proxyHost=www.google.com 
-Dhttp.proxyPort=80

```

But nothing works and I didn't find anything helpful on google seeming like I'm the only one with that problem.

Details:

```

There is nothing to install or update.

```

I'm using a lot of dev tools without a problem and Android Studio is now the first one with connectivity issues.

The XML files mentioned I can access via browser without a problem.
