Can't send requests to https urls with apify proxy

This is my first time subscribing to a proxy provider and I went with Apify Creator Plan.

My problem is on testing, I can only send requests to http urls, it works until I change to https then it doesn't. Here's a snippet:

import requestsimport dotenvpassword = dotenv.get_key('.env', 'APIFY_PROXY_PASSWORD')group = 'auto'proxy_url = f"http://groups-{group}:{password}@proxy.apify.com:8000"proxy_handler = {"http": proxy_url,"https": proxy_url,}r = requests.get('http://httpbin.org/ip', proxies=proxies, timeout=5)print(r)print(r.json())

Once I change it to https://httpbin.org/ip I get a proxy Error:requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='httpbin.org', port=443): Read timed out. (read timeout=5)

I've seen a lot of similar question about http proxy "tunneling" & that they send a CONNECT request, but none actually helped me understand why this happens with https only or solve my issue.
