My database.yml looks like this:

production:
adapter: mysql2
encoding: utf8
database: ebdb

host: aaashxwkmkl2su.cob702nyjvgo.ap-southeast-1.rds.amazonaws.com
port: 3306
username: aa58hsbjqdy3se
password: ********

I have given db username as what I see in ‘DB Instance Identifier’ field for my RDS instance(screenshot attached). The password I am providing is same as what I provided while creating this RDS instance using eb command line tool. I also reset the password again to same value in “New Master Password” field in the attached screenshot to confirm if there are any credential issues. But that didn’t help.

I am clueless about this error. Can someone please help me in resolving this issue?

Thanks.

The default username is not the db instance identifier. The default is awsuser but this can be set to anything when creating the database. If you’re using elasticbeanstalk then the relevant connection details should be available in the environment ( http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_Ruby.rds.html#create_deploy_Ruby.rds.newDB )
