Graylog3 not starting

Hi All,

I was trying to install Graylog3. After providing configurations, I was trying to start it… But Graylog isn’t starting. When I check logs… I found the below:

2019-08-03 21:05:32,216 INFO : org.graylog2.bootstrap.CmdLineTool - Loaded plugin: AWS plugins 3.0.2 [org.graylog.aws.AWSPlugin]

        at org.graylog2.bootstrap.Main.main(Main.java:50)

It stops here and never proceeds further.

Research what I have done so far:
When I google it I got few suggestions as node-id is missing but how can we generate it. In graylog2 it creates on it’s own right?

Please post us your suggestions, Thanks to all in-advance !!!

Is this a clean install or an upgrade?

Hi Mike,
It’s a clean install
