Localhost MongoDB Connection with Mongoose not working

I’m trying to connect to my MongoDB localhost but it just won’t connect. What happens is when I go to /admin, it just keeps loading and I get no messages, no nothing in the logs. I have no idea why. This is my router file that uses the connection:

const express = require('express');
const debug = require('debug')('app:adminRouter');
const mongoose = require('mongoose');
const users = require('../data/users.json');

const adminRouter = express.Router();

adminRouter.route('/').get((req, res) => {
    const url = "mongodb://localhost:27017"; // process.env.DBURL
    const dbName = "workplace_incident_reporter";

    (async function mongo(){
        let client;
        try {
            client = await mongoose.connect(url, 
                { useNewUrlParser: true, useUnifiedTopology: true });
            debug('Connected to mongoDB');

            const db = client.db(dbName);

            const response = await db.collection('Users').insertMany(users);
            res.json = response;
        } catch (error){
            debug(error.stack);
        }
    })
});

module.exports = adminRouter;

    I changed the URL from mongodb://localhost:27017 to mongodb://127.0.0.1:27017

    Your function mongo doesn’t run that way! change it into something like this:

    const db_url = 'mongodb://localhost:27017'
const db_main = 'db-main'

const connectDB = mongoose.connect(
  `${db_uri}/${db_main}`,
  {
    useNewUrlParser: true,
  },
  (err) => {
    if (!err) {
      console.log("MongoDB Connection Succeeded.");
    } else {
      console.log("Error in DB connection: " + err);
    }
  }
)

    Please consider that you can call the mongoDb connection once at the server.js file
