I have Nginx (1.9.12) setup and working fine with HTTP/2 on host-a. I  
can  
establish HTTP/2 connections to host-a with any web browser. I also have  
HTTP/2 and proxypass setup on host-b. I can proxy HTTP/1.1 requests from  
host-b to host-a with any web browser. I can also establish HTTP/2  
connections with host-b using any web browser. However, I can’t get the  
proxy request from host-b to host-a to talk HTTP/2. The connection  
between  
host-b and host-a doesn’t utilize the TLS ALPN extension so that the h2  
protocol can be used. A packet capture shows that HTTP/1.1 is used for  
the  
proxy connection between host-b and host-a despite the fact that virtual  
host on host-a is configured to only accept h2 connections. Is there a  
way  
to force the use of the TLS ALPN extension?

Thanks for your time,  
Russel

As far as I know HTTP2 is only for client-server communication in Nginx.  
Server to server connections remain at HTTP 1.1
