Issue with MySQL connection

Hello everyone!

I’m having an issue when trying to connect to a external MySQL database, with the error:

Connection issue: SQL Database Connector issue: Connection attempt failed: Access denied for user ‘xxxxxx’@‘’ (using password: YES)

I read some posts here in the forum, saying to setup a firewall rule in AWS, to allow any IP adress to connect, but I’m not sure how to do that.
