Python Proxies Returning Connection Error

Question

I've seen hundreds of posts with this same question but none of the answers ever work. I've tried doing everything on the post answers and they all don't work.

import requests
import random

def get_proxies():
  request = requests.get('https://proxylist.geonode.com/api/proxy-list?limit=50&page=1&sort_by=lastChecked&sort_type=desc')
  request = request.json()['data']
  proxies = []
  for proxy in request:
    proxies.append(f'{proxy["ip"]}:{proxy["port"]}')
  return proxies

def format_proxy(proxy):
  return {'http': proxy, 'https': proxy}

if __name__ == '__main__':
  proxies = get_proxies()
  response =requests.get('https://api.ipify.org/', proxies=format_proxy(random.choice(proxies)), headers={"User-Agent": "Opera/9.80 (X11; Linux x86_64; U; de) Presto/2.2.15 Version/10.00"})
  print(response.text)

I'm scraping the proxies from https://geonode.com/free-proxy-list/ and I keep getting the same error. I'm scraping new proxies every time I send a request so they shouldn't be invalid yet it's giving me a "max retry exceeded error"
