HTTP/2 and HTTPS

[Roswebnet]

Thank you for your fast response.

However, could you please provide an example of "IP on the listen
directive"

I am accessing content from Firefox like https://192.168.1.162 for https
connection and
https://192.168.1.163 for http2. Moreover, those ip also accessible by
http:// and served also well, but in my opinion it should gave some kind of
error, because those server names do not have port 80 configured.
