As I said, the rest is done. Web browsers require 'SSL' for http/2, so if you've set up the certificate, then you already have http/2. Check it using your web browser dev tools.

    marty Hello Marty, thank you for your response. I have an SSL certificate, but in page speed insights, I have a warning.

      What does it say when you click the down arrow (on the right hand side) for more information?

        That's odd - all my sites just worked out of the box.
        Have you made any changes to your sites config? What's in /var/www/yoursite.com/conf/nginx/ssl.conf (it should say listen 443 ssl http2; etc, and there should be an include for this folder in your main site config)?

          marty may be he is using his own SSL cert , not generated by wordops

            For the SSL certificate, I use cerbot because --letsencrypt --force doesn't work for me.
            I have Cloudflare DNS only.
            On another website for my friend working flawless,
            What can I do? I have a backup for WordPress. Delete the website and start from the beginning?
            And if SSL doesn't work again?
            Now can I add HTTP/2 and how?
            Which is the best solution?
            Finally, just add listen 443 ssl http2; Done!
