ConnectTimeout occurs when the website you are trying to connect to doesn't respond to your connect request in time. You can simulate this error for a website by using a custom connect timeout in your request.get() call:
import requests
# Timeout is in seconds
connect_timeout = 0.1
read_timeout = 10
response = requests.get("https://scrapingbee.com/", timeout=(connect_timeout, read_timeout))
If you are sure your IP is not being blocked by the website and the website is working fine, then you can fix this error by increasing the connect timeout value:
import requests
connect_timeout = 6
read_timeout = 10
response = requests.get("https://scrapingbee.com/", timeout=(connect_timeout, read_timeout))
