I am having a trouble with using the request() method of Session class in Python.

In my backend, if I call an API with request()

Method first time there is the response. But if I call this method after 5 minutes, it throws:

Connection aborted, Remote disconnected (Remote end closed connection without response)

But if I call the same API with Postman, it always returns response.
Here is my code snippet.

from requests.sessions import Session as _Session
class Session(_Session):
    def __request(method, url, json, data, files, params):
        try:
            response = self.request(headers, method, url, json, data, files, params)
        except Exception as e:
            print(str(e))

I have checked the headers and it was the same in any cases.

What might be the issue?

I have added timeouts=10 but it was not working.
