Is Mongoose Down? (nvm, it's my fault)

Here are few lines of my code

app.route('/api/shorturl/new')
  .post((req, res) => {
    urlData.findOne({ name: 'counter' }).select(['count']).exec((err, data) => {
      if (err) return console.log(err)
      console.log(data.toObject().count)
      })
   })

I got MongooseError: Operation urldatas.findOne() buffering timed out after 10000ms

Is Mongoose Down? Few hours ago my code is working just fine.

Turns out theres a conflict in my localhost:3000.
