How to switch to HTTP/2?

Question

Apache HTTP Server

Hello. I'll get straight to the point:
There is an Apache2 + NGINX web server (works as a proxy). It is necessary that the server works under the HTTP/2 protocol. Apache2 latest version. I set it in the config to work using the HTTP / 2 protocol, but it still works using HTTP version 1.
How to solve this problem?
And in order not to produce questions, I also want to ask: How to connect an SSL certificate to VestaCP?
Thanks in advance!
