Hi @kesifalaraskey

Can you filter your log for “ERROR” and paste it here once again…those “infos” and “warns” helps almost nothing to troubleshoot your problem…

No ERROR line is showing in logs

From Graylog Server, can you access (ping, telnet) your ES in AWS?

@kesifalaraskey

Is this a duplicate post?

No, some difference is there between two.
This one has clear view on what action error is occuring and also all other things are working properly just on adding AWS ES endpoint in conf file the thing stop working.

How can i do that?
because after adding AWS ES endpoint the server is not starting and also server.log stuck at
this last line

Oh I see, For a minute I thought it was the same problem. My apologies.

@kesifalaraskey

Hello,

Can you show your Graylog configuration, make sure you keep private configuration private.

This might help with server.conf file.

grep -v "^#\|^$" server.conf | sed -e "s/#.*$//g"

Also your Elasticsearch configuration file.

grep -v "^#\|^$" elasticsearch.yml | sed -e "s/#.*$//g"

This will help us find your issue or at least narrow it down.

Thanks

Edit:
Make sure ES is running first and in “Green” as I showed in the other post.
Then install/start MongoDb. Last start Graylog Service. Not sure if that will help but doesnt hurt to try.

Thanks you all,

I have fixed the thing just by adding elasticsearch version manually in server.conf file.
