Looks like mongoDB isn’t starting.

how did you installed Graylog?

You need MongoDB and Elasticsearch up an running to be able to use Graylog - In addition the logfiles in /var/log might give you some idea what had happened.

It looks like i need to update my database data to the new version of mongodb, any good guides on how to do that?

Stepped forward from mongo 2.6 to 3.6 and now the upgrade works perfectly.
