Nginx not working with http/2?

Question

Nginx

https://www.digitalocean.com/community/tutorials/h...
Nginx 1.10.3, ssl from Lets Encrypt. I installed everything, set it up, check the protocol, it shows that it uses http/1.1 .
I tried to clear the cache, incognito in chrome is still the same, checked in mozilla, still the same, uses http 1.

Indicates that the server supports http2.

Indicates that This browser is not HTTP/2 enabled.

Please tell me how to fix it?

Answer 1

server {
listen 443 ssl http2;
server_name *.com;
No problem.
Give me the full config, even ssl won't work for you now
Nginx can't communicate over http/2.0 via proxy_pass Better
