How to set up HTTPS and HTTP/2 in Nginx?

Question

Nginx

Good day!
The task is to configure HTTP2 and HTTPS on the NGINX server.
HTTPS is up and running, but HTTP2 is having trouble, it just doesn't work.
Ubuntu 1404
Nginx 1.10.0
nginx settings

server {
    listen 80;
    server_name www.mysite.com mysite.com;
    rewrite ^ https://mysite.com$request_uri? permanent;
}
server {
    listen      443 ssl http2;
    server_name www.mysitecom mysite.com;
    ssl    on; 
    ssl_certificate      /home/developer/conf/web/ssl.developer.dev.pem;

    location / {
        root    /home/developer/web/developer.dev/public_html;
    }
    location /error/ {
        alias   /home/developer/web/developer.dev/document_errors/;
    }

    location @fallback {
        proxy_pass      http://172.31.1.100:8080;
    }

    location ~ /\.ht    {return 404;}
    location ~ /\.svn/  {return 404;}
    location ~ /\.git/  {return 404;}
    location ~ /\.hg/   {return 404;}
    location ~ /\.bzr/  {return 404;}

    include /home/developer/conf/web/nginx.developer.dev.conf*;
}

Thank you in advance!

Answer 1

Found the answer to the question myself.
For http2 to work, nginx requires OpenSSl version 1.0.2 and later.
I have Ubuntu 1404, the latest version they have now is 1.0.1f-1ubuntu2.
On the OpenSLL site, the latest stable version to date, 1.0.2, was released on March 3rd.
Thank you all for your help, issue closed.

Answer 2

1. How do you determine that http2 is not working?
2. Does your version of nginx support http2?
