ECONNREFUSED 134.122.99.37:5432 [SequelizeConnectionRefusedError]

I am new to the process of setting up a server and connecting my database to it. What I am trying to do: I want to start running my node js application by using npm start.

The Problem: But I get this error:

error from routes.js ConnectionRefusedError [SequelizeConnectionRefusedError]: connect ECONNREFUSED 134.122.99.37:5432 . . . original: Error: connect ECONNREFUSED 134.122.99.37:5432 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1141:16) { errno: ‘ECONNREFUSED’, code: ‘ECONNREFUSED’, syscall: ‘connect’, address: ‘134.122.99.37’, port: 5432 }

To start running on the digital ocean IP address the replaced localhost with the ‘134.122.99.37’.

My config file:

module.exports=new Sequelize(‘db_name’,‘user_name’,‘password’,{ host:‘134.122.99.37’, dialect:‘postgres’, operatorAliases:false, pool:{ max:5, min:0, acquire:30000, idle:10000 }, });

Any good resources/tutorials would be a major help.

Thanks in advance
