Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it

Hey Team!

I want to follow people using InstaPy, but something is keeping my code from running.

This is the code:
....
# get an InstaPy session!
session = InstaPy(username=insta_username,
password=insta_password,
headless_browser=True,
multi_logs=True)

with smart_run(session):
""" Activity flow """
# general settings
session.set_relationship_bounds(enabled=True,
potency_ratio=None,
delimit_by_numbers=True,
max_followers=6000,
max_following=3000,
min_followers=30,
min_following=30)

session.set_dont_include(["friend1", "friend2", "friend3"])

ammount_number = 50
session.follow_user_followers(['refikanadol', 'nvidia', 'lilmiquela', 'bruthethe', 'tiltgamer', 'wuyckhuyse'],
amount=ammount_number, randomize=False, interact=True)

....

When ran, the quickstart logs in and starts by going to refikanadol's followers, but then the session is interrupted.

Here's the error:
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

Do you know the fix for this?

Thanks!
Tijana
