today i couldnt access my ELK page, only getting 502 bad gateway from nginx. i havent changed anything in nginx, but after some research and testing i found out that it has something to do with 5601. i did a netstat -tapen | grep ":5601" to see who was listening on port 5601 and it didnt return anything, i suspect kibana is not listening to this port now. even though service kibana4 is up and running.
thoughts guys? thanks.
