this is my code:

Procfile:

web:node server

.gitignore:

node_modules/

server.js

const express = require('express')
const morgan = require('morgan')
const cors = require('cors')
const connectDB = require('./config/db')
const passport = require('passport')
const bodyParser = require('body-parser')
const routes = require('./routes/index')


connectDB()

const app = express()

if(process.env.NODE_ENV === 'development') {
    app.use(morgan('dev'))
}

app.use(cors())
app.use(bodyParser.urlencoded({extended: false}))
app.use(bodyParser.json())
app.use(routes)
app.use(passport.initialize())
require('./config/passport')(passport)

const PORT = process.env.PORT || 3000

app.listen(PORT, console.log(`Server running in ${process.env.NODE_ENV} mode on port ${PORT}`))

package.json:

{

    "nodemon": "^2.0.19",
    "passport": "^0.6.0",
    "passport-jwt": "^4.0.0"
  }
}

For now, I got this:

If I write on the command prompt: "heroku restart", It works

And if I write on the command prompt: "heroku logs --tail", it shows me again, the first image, it doesn't work

How to fix this error

Thank you in advance

CodePudding user response：

I'm assuming you are using mongodB atlas. You need to whitelist your IP address. To do that, head over to your network access tab, and include an IP address 0.0.0.0/0. This is a wild card IP address that would allow all IP addresses with the correct credentials to access your DB.

As such:

Note: This whitelists all IP addresses. It's alright when testing. But when going into production, you might want to whitelist only IP addresses that should have access to the cluster...for security purposes.
