FastAPI Failed to call other HTTP calls using aiohttp

[Riki-1mg]

Problem: I have 2 micro service one is written in Flask (service A)(python3.4) and another on is in FastAPI (python3.6) (Service B)
Used following module for inter service communication.
- aiohttp
Service run very smoothly for 2-3 hours, then it suddenly start breaking while connecting to service B

code sample:

base_http_handler.py

class BaseHttpHandler:
aiohttp_session_client = ClientSession()

async def request(cls, method: str, path: str, data: dict = None, query_params: dict = None, timeout=None,
              headers=None, response_headers_list=None):
    try:
        async with cls.aiohttp_session_client.request(method, str(url), data=data, headers=headers,
                                                  timeout=cls.request_timeout(timeout)) as response:
            payload = await response.json()

    except Exception as e:
        logger.info(e)

Can you please help me out ?
