Connecting to MySQL Database on Amazon with Sequel Pro vs. Terminal

The problem:

I'm trying to create a python script on my local computer, that will connect to a MySQL database on an amazon server.

What's the difference between this (which works):

And this:

Which returns this: Can't connect to MySQL server on '**************.rds.amazonaws.com' (60)

What I tried:

1.) Telnet to **************.compute.amazonaws.com:

Trying **************...

telnet: connect to address **************: Operation timed out

telnet: Unable to connect to remote host

2.) Logged on to **************.compute.amazonaws.com via ssh, and tried to mysql -h there:

mysql -h profilerdev.cijoya8mp1vj.ap-southeast-1.rds.amazonaws.com ERROR 1045 (28000): Access denied for user '*******'@'*************.compute.internal' (using password: NO)

3.) Ran my script (above) on the server:

Error 1045 Access denied for user '*******'@'*************.compute.internal' (using password: YES)

Am I missing anything?
