Почему у меня не поддерживается прокси схема?

Question

[Tayrus0]

Есть код

proxis = {'https':'188.225.27.151:3128'} 
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 YaBrowser/19.10.3.281 Yowser/2.5 Safari/537.36'}

autoru = requests.Session(); response = autoru.get('https://auth.auto.ru/login/',proxies=proxis); CSRF_token = response.cookies['_csrf_token']; autoru.headers.update({"x-csrf-token": CSRF_token}); autru = autoru.post("https://auth.auto.ru/-/ajax/auth/",proxies=proxis,headers=headers, json={"items":[{"path":"auth/login-or-register","params":{"phone":f"{phone_number}","retpath":"https://auto.ru/voronezh/cars/used/?utm_source=yandex_browser-newtab&utm_medium=cpm&utm_campaign=ybro_rk-rus-r225-aug-2019_rus-r225_view&utm_content=728x90-612b-static_612b-fomenko-white-naidi-svou-mashinu_rus-r225"}}]})

На одной машине он работает, на другой выдает ошибку:

Traceback (most recent call last):
  File "gg.py", line 10, in <module>
    autoru = requests.Session(); response = autoru.get('https://auth.auto.ru/log

Почему и как исправить?
