In nginx, you have to setup reverse proxy config for zeppelin websocket port in addtion to normal zeppelin http port. you can find instruction on nginx documentation site for this kind of setup.
please refer this url: https://www.nginx.com/blog/websocket-nginx/ if it wont helps, i can share my config :) Works 메일 앱에서 보냈습니다. -----Original Message----- 보낸사람:"yupeng" <yup...@qfpay.com> 받는사람:"users" <users@zeppelin.incubator.apache.org> 참조:"dev" <d...@zeppelin.incubator.apache.org> 날짜: 2015.09.02 오후 04:10:55 제목: Re: Zeppelin not accessible behind a proxy server Hi, I meet the same problem,While I can access the Zeppelin URL by the proxy it shows in disconnected status every seconds.and i curl to my websocket port and get empty result.
