Websockets not working for proxy_pass

[sanket.1985@…]

I am trying to put Nginx in front of Zeppelin. For the same, have done configuration of Zeppelin for Nginx based on their documentation. While am trying to follow the steps, it seems that Websockets are not working with Zeppelin.

Reference guide followed is at: ​https://zeppelin.apache.org/docs/0.7.3/security/authentication.html

Configuration of default.conf file for Nginx is as below:

        location /zeppelin/ {
            proxy_pass http://104.211.216.218/;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-NginX-Proxy true;
            proxy_redirect off;
        }

        location /zeppelin/ws {
            proxy_pass http://104.211.216.218/ws;
            proxy_http_version 1.1;
            proxy_set_header Upgrade websocket;
            proxy_set_header Connection upgrade;
        }

If you think this is a bug in nginx, please provide details on why do you think it is indeed bug in nginx, and not a bug in Zeppelin and/or misconfiguration in your setup. If you need help with configuring nginx, consider using ​support options available.
