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

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
