http2 module nginx not working

Question

I have some problem with enable http2 protocol in nginx. Site writes on Laravel 5 (but I think this doesn\'t matter).

First, I upgrade nginx version.

Answer 1

Google Chrome now insists on using ALPN for HTTP/2 so you need to build Nginx with OpenSSL 1.0.2 or above (which isn't available as a packaged version on most platforms yet so you might have to install manually from source for now).

Check if it works for HTTP/2 in Opera and if so that's your problem.

Answer 2

I didn't immediately see any errors in your config, so first, the obvious: did you reload/restart Nginx?

service nginx restart

Then, I would double-check the results you're getting in Chrome by using a website such as https://tools.keycdn.com/http2-test. I would also check the server logs and see what HTTP version Nginx is reporting is being used.
