Super new to this all so please forgive the ignorance here, but I've followed this tutorial to install NodeBB on a DO droplet, and I've got to the 'Welcome to NodeBB' part of the installation. But I'm not sure what I'm doing wrong or how to correct it with regards to these errors:
28/2 05:08  - error: NodeBB could not connect to your Mongo database. Mongo returned the following error: connect ECONNREFUSED
28/2 05:08  - warn: NodeBB Setup Aborted.
Error: connect ECONNREFUSED
at errnoException (net.js:901:11)
at Object.afterConnect [as oncomplete] (net.js:892:19)
I just pressed Enter when asked about the MongoDB name and password etc. because the guide linked above mentions not to add any info just to leave this all blank.
Any assistance would be appreciated.
