Solution 1: Use urllib3 1.25.11

In urllib3 version 1.25.11 working perfectly. So you can install urllib3 1.25.11 by following command line.

pip install urllib3==1.25.11

Solution 2: urllib3 the main schema changed

Actually urllib3 the main schema of proxy was changed and if you are using urllib3=1.26.4 then follow the below code.

Here is the old code before schema of proxy was changed

proxyArr ={
    'http':'http://my correct proxy here: myport',
    'https':'https://my correct proxy here: myport'
}
self.response=requests.get(url=url,headers=self.headers,proxies=proxyArr )

Here is the new code after the schema of proxy was changed.

proxyArr = {'https': 'http://8.88.888.8:8888'} 

self.response=requests.get(url=url,headers=self.headers,proxies=proxyArr )
