Database is connecting from SQLyog, but not from nodejs - mysql

Question

I am able to connect database from SQLyog, but when connecting from Node.js getting following error:
Database IP : 10.0.0.200
Error when connecting to db: { Error: ER_DBACCESS_DENIED_ERROR: Access denied for user 'myuser'#'10.0.0.100' to database 'db_new'

errno: 1044,
sqlMessage: 'Access denied for user \'myuser\'#\'10.0.0.100\' to database \'db_new\'',
sqlState: '42000',
fatal: true }
Code to connect to DB is as follows,
connection = mysql.createConnection({
host: settings.dbhost,
user: settings.user,
password: settings.password,
database: settings.database
});
Any ideas on how to fix this?

When encountering this issue, one common problem is that the user isn't being GRANTED with all the privileges. To grant with all the privileges, you may execute an SQL command as mysql suggests,
mysql> show grants;
+-------------------------------------------------------------------------------------------------------------+
| Grants for RollingRidge#% |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'RollingRidge'#'%' IDENTIFIED BY PASSWORD '*REDACTED' |
| GRANT ALL PRIVILEGES ON `rollingridge`.* TO 'RollingRidge'#'%' |
+-------------------------------------------------------------------------------------------------------------+
Hope this helps.
