No response when trying to run Python proxies

Question

I’m trying to write a code to make my own Scrapping on the Web and I’m trying to implement the proxy rotation, but I’m not getting any results. I’ve checked many websites and forums about this problem, but I can’t make it work. Here is part of the code I’m using, the list of proxies comes from the site https://www.sslproxies.org/

p = get_proxies()
p_pool = cycle(p)
url = 'https://youtube.com'

for i in range(1,50):
    proxy = next(p_pool)
    print("request #%d"%i, proxy)
    try:
        response = requests.request(url, proxies={"https": proxy, "http": proxy}, timeout=10)
        print(response.json())
    except:
        print("Skipping. Connection error")

I always get the same error message:

request #1 118.200.73.124:8080
Skipping. Connection error
request #2 103.242.44.80:8080
Skipping. Connection error
request #3 82.200.233.4:3128
Skipping. Connection error
request #4 109.75.47.248:53422
Skipping. Connection error
request #5 181.117.176.236:61358
Skipping. Connection error

How can I make this code work?

Thank you very much!
