nginx-proxy: Websocket connection can't be made

I’m trying to run an instance of Jupyter on my Digital Ocean server using this container: https://hub.docker.com/r/jupyter/notebook/. I have nginx-proxy configured to connect to that container with the correct hostname, but despite editing the notes.rooday.com_location file in /etc/nginx/vhost.d/, websocket connections can’t be made.

This is my notes.rooday.com_location file:

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;

This is the error Chrome gives me when I open a jupyter iPython notebook and attempt to make a websocket connection:

WebSocket connection to 'ws://notes.rooday.com/api/kernels/677b0d97-20cd-4b1a-b499-c9b513b859d9/channels?session_id=6E236819286E46D38B03D34047252F48' failed: Error during WebSocket handshake: Unexpected response code: 400

Very strange, this my dump when it works:

$ docker run --rm -e VIRTUAL_HOST=docker-machine jupyter/notebook

$ docker exec desperate_torvalds cat /etc/nginx/conf.d/default.conf

# scheme used to connect to this server
map $http_x_forwarded_proto $proxy_x_forwarded_proto {
  default $http_x_forwarded_proto;
  ''      $scheme;
}
# If we receive Upgrade, set Connection to "upgrade"; otherwise, delete any
# Connection header that may have been passed to this server
map $http_upgrade $proxy_connection {
  default upgrade;
  '' close;
