sslv3 alert bad record mac

python 3.8
When I visit the https website with its own certificate Some websites cannot be accessed

when I modify the code as follows is works

I think there is a problem with ssl adaptation. Please help me
```
import requests

from requests.adapters import HTTPAdapter
from urllib3.poolmanager import PoolManager
import ssl

class TLSAdapter(HTTPAdapter):
    def init_poolmanager(self, connections, maxsize, block=False):
        self.poolmanager = PoolManager(
            num_pools=connections,
            maxsize=maxsize,
            block=block,
            ssl_version=ssl.PROTOCOL_TLSv1_1  
        )

session = requests.Session()
session.mount("https://", TLSAdapter())
response = session.get("[https://49.249.126.138",](https://49.249.126.138%22%2C/) verify=False, timeout=5)

print(response)
```

## Expected Result

<Response [200]>

## Actual Result
