I know that Graylog 3.0 is still a test version but I have problem running it.
I downloaded GR 3.0 and upgraded graylog on some test Centos systems systems from 2.5 version. The server seems to start OK, but iREST and WEB are now listening on default IP address. But I didnt changed that in config file, there it it still local IP:
2019-01-21T11:31:18.126+01:00 INFO [NetworkListener] Started listener bound to [127.0.0.1:9000]
2019-01-21T11:31:18.128+01:00 INFO [HttpServer] [HttpServer] Started.
2019-01-21T11:31:18.128+01:00 INFO [JerseyService] Started REST API at <127.0.0.1:9000>
Can this be related to version 3.0 ? Maybe I made some mistake during upgrade and config change.
