Can't upstream https requests to cowboy 2.5 via nginx

Correct me if I’m wrong but I don’t think I’m passing http2 requests.

[MY IP] - - [02/Nov/2018:20:15:46 +0000] "GET / HTTP/1.1" 400 0 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.67 Safari/537.36"```

Also I did just write this and this current ticket is my attempt to rollback from http2 but I’m seeing the same issues I had then.
