I have been testing Graylog for an in house project which has been receiving logs from a single host successfully for a few weeks now. This morning I have tried to look at it and it was non responsive. I have rebooted the VM and was able to login in briefly but I now get “Server currently unavailable” with the message "cannot GET [http://XXX.XXX.XXX.XXX:9000/api/](http://XXX.XXX.XXX.XXX:9000/api/) (500).

Anyone got any ideas?

Hello

Welcome our community!

It can caused by many things.  
So check the followings:

- mongodb service’s state
- elasticsearch’s state
- mongo and elasticsearch’s logs.
- graylog’s log files

Maybe it helps to find the lofgiles.  
[https://docs.graylog.org/en/3.1/pages/configuration/file\_location.html](https://docs.graylog.org/en/3.1/pages/configuration/file_location.html)

(OK, maybe elasticsearch doesn’t couse this type of error…)

Any idea of the commands I need to use to check this? I have logged into the console but I cant seem to find anything for version 3.2.
