Cannot read the cerficate

[Nuno C]

Hi there.

First of all, thanks for the plugin and all the work.

I'm trying to put the example working, so I'm accessing the following url:
http://localhost:8080/examples/example.php

Here's the folder configuration:
https://i.gyazo.com/943a8d0c7326c2046e7063c62b79f260.png

Accessing that url, it returns to me:
Error: Could not read the certificate

Any help?

Thanks
