Hello. Since 0.5.5, Zeppelin uses single port for REST and websocket. so Could you try to use same port like follow Nginx configuration?
server { listen 80 ; server_name _; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $proxy_protocol_addr; proxy_set_header X-Forwarded-For $proxy_protocol_addr; proxy_pass http://backend; } location /ws { proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://backendWS <http://backendws/>; } } I am fixing the documentation.
