Currently it does not seem possible to have vweb running with SSL enabled
It would be great if you could add a way to use/detect installed certificates in vweb
These days, it would be better to have auto "Let's Encrypt" support built-in. That would be support for obtaining a certificate from Let's Encrypt, auto-renewal/replacement on expiration, etc.
Optionally, you should be able to specify a certificate and turn off the Let's Encrypt support.
I think it's much better to use nginx for this.
It'll be supported, but it's definitely not a priority.
