Managing MUP Deployed Mongo Instance with MMS

I’m trying to use MMS ( to manage/backup my mongo database. I previously used MUP to deploy my app to a Digital Ocean Droplet, installing mongodb locally on my machine. MMS asks for a host and port for the mongo database server, but per the MUP docs, the mongo database can only be accessed internally on the server via SSH. Is it possible to connect MMS to my mongo database, or do I need to re-deploy my app with a previously configured Mongo db? Sysadmin isn’t my strong suit here, so if anyone could provide any additional background on this, it would be greatly appreciated! Thanks!

Edit: I should note that I tried various versions of my server’s host name/IP + the default mongo port, but didn’t have any luck.
