1979	listen 80 http2; combined with proxy_pass http:// brakes website	Hans-Cees		"Hi,

I do not know if this is how nginx should behave, but it surprised me and caused some searching.

when using 
listen 80 http2;

together with nginx as reverse-proxy nginx did not connect to the proxied-site, and answered with files my browser tried to download, since no mime type was known.

Perhaps port 80 http2 should not be accepted as a valid config?

I am running nginx with docker on a debian vm. 
image: nginx:stable-alpine
