How do I configure PyMySQL connect for SSL?

Question

I'm trying to connect my database using SSL with PyMySQL, but I can't find good documentation on what the syntax is.

These credentials work in Workbench and with the CLI, but I get this error when using PyMySQL.

Can't connect to MySQL server on 'server.domain.com' ([WinError 10061] No connection could be made because the target machine actively refused it)")

db_conn = pymysql.connect(
    host=db_creds['host'],
    user=db_creds['user'],
    passwd=db_creds['passwd'],
    db=db_creds['db'],
    charset=db_creds['charset'],
    ssl={'ssl':{'ca': 'C:/SSL_CERTS/ca-cert.pem',
                'key' : 'C:/SSL_CERTS/client-key.pem',
                'cert' : 'C:/SSL_CERTS/client-cert.pem'
                }
        }
)

If I shut SSL off and drop the SSL parameter, I can connect unsecured just fine. What am I doing wrong with the SSL parameter?

Edit: PyMySQL now wants ssl parameters listed like this instead of in a dict.

db_conn = pymysql.connect(
     host=db_creds['host'],
     user=db_creds['user'],
     passwd=db_creds['passwd'],
     db=db_creds['db'],
     charset=db_creds['charset'],
     ssl_ca='C:/SSL_CERTS/ca-cert.pem',
     ssl_key='C:/SSL_CERTS/client-key.pem',
     ssl_cert='C:/SSL_CERTS/client-cert.pem'
                          )

Thanks for the help everyone. The syntax listed in the question is right, but the server I was attempting a connection to was using a non-standard port. I needed to add

port = db_creds['port']

Thanks, MannyKary, for the clue.
