Nginx 1.9.11 and OpenSSL 1.0.2G - HTTP2, but no ALPN negotiated.

[Andrew Hutchings]

Hi,

On Ubuntu 14.04 NGINX is built with OpenSSL 1.0.1 so is not built with 
ALPN support. If you have installed OpenSSL 1.0.2 you can recompile 
NGINX to use this and gain the ALPN support.

In most cases HTTP/2 with NPN in OpenSSL 1.0.1 will work for now.

Kind Regards
Andrew
