Is it possible to connect local django project to MySql running on AWS EC2? How?

What I tried:

• Installed the MySql server on the EC2 instance.
• In the security group of the instance added an inbound rule to connect over shh from all source
• Created a database and user
• Given that user all permissions using GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
• Created a Django project using django-admin startproject mysite and installed mysqlclient
• in project settings, I changed the default database from SQLite to

{
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'dbtest',
        'USER': 'root',
        'HOST': '{IPv4 Public IP of the Instance}',
        'PASSWORD': 'password',
}

Now when I run python manage.py runserver it gives me the error

django.db.utils.OperationalError: (1045, "Access denied for user 'root'@'xxx.xx.xxx.xxx' (using password: YES)")

Then I granted all privileges to this specific IP as well using: GRANT ALL PRIVILEGES ON *.* TO 'root'@'xxx.xx.xxx.xxx' WITH GRANT OPTION;

Still no luck.Same Error.

You also have to set MySQL configuration for allowing it to accept remote connection in mysqld.cnf file add change following value.

[mysqld]
bind-address    = 0.0.0.0
# skip-networking

then restart MySQL Service.

and you also have to add Application port in Security Group of EC2 instance
