Issue with connecting my express server on heroku to the remote mySQL - heroku

Question

I'm trying to deploy my express server on Heroku which needs to connect to the remote MySQL database.
I used 'heroku config:add DATABASE_URL=mysql://dbusername:dbpassword#databasehostIP:databaseserverport/databasename with the correct information but still it tries to connect through wrong address.
I also used 'heroku config:add EXTERNAL_DATABASE_URL=mysql://dbusername:dbpassword#databasehostIP:databaseserverport/databasename with the correct information but still it tries to connect through wrong address.
In my Heroku app panel under 'setting' in 'Config Vars' section I see that DATABASE_URL and EXTERNAL_DATABASE_URL appeared with correct information. but in heroku log I still see the wrong information
This is my sequelize variable on the express server:
const sequelize = new Sequelize('dbName', 'USER', 'Password', {
host:"hostAddress",
dialect: 'mysql'
}
But I see the following on Heroku log:
2019-02-16T18:31:42.231390+00:00 app[web.1]: Unhandled rejection
SequelizeAccessDeniedError: Access denied for user
'USER'#'ec2-54-162-8-141.compute-1.amazonaws.com' (using
password: YES)
How can I change 'ec2-54-162-8-141.compute-1.amazonaws.com' to the remote MySQL host address?

Try setting your variable with something like this:
if (process.env.DATABASE_URL) {
const sequelize = new Sequelize(process.env.DATABASE_URL, {
define: {
freezeTableName: true, // don't make plural table names
underscored: true // don't use camel case
},
dialect: 'mysql',
dialectOptions: {
ssl: true
},
logging: true,
protocol: 'mysql',
quoteIdentifiers: false // set case-insensitive
});
} else {
console.log('Fatal error: DATABASE_URL not set');
process.exit(1);
}
