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

Resolution: duplicate
Status: newclosed

Using listen ... http2; without ssl configures listening socket to use HTTP/2 with prior knowledge. Browsers are not able to talk via sockets configured this way. Duplicate of #808.
