Handshake operation timeout

For my project I am using aysnchronous python driver ‘motor’. There is successful connection to database most of time. When I look AWS cloud watchlogs , I found a error connecting to database in some logs.

Traceback (most recent call last):
File "/var/task/pymongo/pool.py", line 1040, in _configured_socket
sock = ssl_context.wrap_socket(sock, server_hostname=host)
File "/var/lang/lib/python3.8/ssl.py", line 500, in wrap_socket

During handling of the above exception, another exception occurred:

raise NetworkTimeout(msg)
pymongo.errors.NetworkTimeout: SSL handshake failed: cluster0-shard-******mongodb.net:******: _ssl.c:1114: The handshake operation timed out

I have used this import in code. to show return type. Whether does it cause issues?

from pymongo.results import DeleteResult

async def delete_data(conn: AsyncIOMotorClient) -> DeleteResult:

My MongoDb url is

MONGODB_URL= mongodb+srv://*******:******@cluster0.****.mongodb.net/{MONGO_DB}?retryWrites=true&w=majority
