How to correctly send a GET request through an SSL tunnel in Python?

Question

Python

On a Debian server, a service (JSON-RPS) with a REST API is running.
To connect to the server via SSL
, you need to write GET requests to the service in Python 3.6.
created a tunnel in Putty. localport--> server: the port on which the service is running.
I form a request:

s = requests.Session()
    url = "https://localhost:3704"

   response = s.post(
        url,
        data=json.dumps(rpc_input),
        headers=headers,
        timeout = 5,
        verify=False)

I get an error

requests.exceptions.SSLError: HTTPSConnectionPool(host='localhost', port=3704): Max retries exceeded with url: / (Caused by SSLError(SSLError("bad handshake: SysCallError(10054, 'WSAECONNRESET')",),))

how do i sign the request?
what needs to be done so that the GET request goes to the service?
