Tell us what’s happening:
Describe your issue in detail here.
It says ‘Database connection should be present’, I think something is wrong with my .env, but the other one in this project as well as the one from the last project worked fine. I’ve been trying to solve this one problem for multiple hours please help!!

Try downloading MongoDB Compass and see if you’re able to connect to your database from there by passing your URI string:

If you need to encode your password (I did):

Thank you Nikola!
I just got Compass, but I’m not sure how it’s supposed to help make the connection between database and project; maybe I’m just burnt out. Where do you suggest I start?
Luckily, no password encoding needed!

Hi QueenOfElves, Compass is a tool for visualizing your MongoDB database. If you’re able to connect to your database from there then that means there’s no issue with your connection string and the problem is somewhere else. Were you able to connect to your database?
