I'm running jupyterhub on RHEL7 with authentication through generic oauth2, apache reverse proxy. I can login, spawn a server and see the environment and launch notebooks. When the notebook launches I can not run it. I keep getting "kernel connecting " errors and messages that the websocket connection has closed early. I added this to my httpd.conf file:

# Use RewriteEngine to handle websocket connection upgrades
  RewriteEngine On
  RewriteCond %{HTTP:Connection} Upgrade [NC]
  RewriteCond %{HTTP:Upgrade} websocket [NC]
  RewriteRule /(.*) ws://127.0.0.1:8000/$1 [P,L]

but still the websocket closes and the kernel will not connect.  Can anyone offer any insight?
