Answer 1

After trying EVERY solution google came up with on stack overflow, I found what my particular problem was. I had edited my hosts file a long time ago to allow me to access my localhost from my virtualbox.

Removing this entry solved it for me, along with the correct installation of mongoDB from the link given in the above solution, and including the correct promise handling code:

mongoose.connect('mongodb://localhost/testdb').then(() => {
console.log("Connected to Database");
}).catch((err) => {
    console.log("Not Connected to Database ERROR! ", err);
});
