RDS MySQL DNS hostname incorrect

I am trying to connect to my RDS MySQL instance using MySql client on a ubuntu terminal. When I type the following command and provide it the database password, I notice that it fails and it seems like it is trying to connect to a different hostname than the one I want it to connect to. What am I missing?

Desired DB Host:

Seems to be trying to connect to:

--user=my-user -p blahblah

Enter password: 
ERROR 1045 (28000): Access denied for user 'my-user'@'' (using password: YES)
