Can't connect to to SQL database with sqlalchemy

See original GitHub issue

I created a Jupyter Lab environment using this Link:

https://mybinder.org/v2/gh/JulianWgs/candas/master?urlpath=lab/tree/

Then I’m trying to connect to a SQL database with sqlalchemy:

from sqlalchemy import create_engine

ip = ""
port = ""
database = ""
engine = create_engine(
    'mysql+mysqldb://{}:{}@{}:{}/{}'.format(
        input("User: "), 
        getpass.getpass("Password: "), 
        ip, 
        port, 
        database), 
    pool_recycle=3600)
connection = engine.connect()

This fails with:

OerationalError: (MySQLdb._exceptions.OperationalError) (2003, "Can't connect to MySQL server on 'XXX.XXX.XXX.XXX' (110)")
(Background on this error at: http://sqlalche.me/e/e3q8)

It works with Google Colab and of course locally.
