I am trying to develop a RAG using AzureOpenAI and CosmosDB
I have created a Azure Cosmos DB for MongoDB (vCore) in azure. I am trying to connect to the db but getting ServerSelectionTimeoutError.

I am Set up the connection through below python code:

from urllib.parse import quote_plus

username = quote_plus("username")
password = quote_plus("password")
server = "service_name.mongocluster.cosmos.azure.com"

mongo_conn = f"mongodb+srv://{username}:{password}@{server}/?tls=true&authMechanism=SCRAM-SHA-256&retrywrites=false&maxIdleTimeMS=120000"
mongo_client = pymongo.MongoClient(mongo_conn)

This code runs successfully with below warning:
C:UsersAppDataLocalTempipykernel_329224156620.py:9: UserWarning: You appear to be connected to a CosmosDB cluster. For more information regarding feature compatibility and support please visit https://www.mongodb.com/supportability/cosmosdb
mongo_client = pymongo.MongoClient(mongo_conn)

Then I try to execute the below code for Set up the DB and collection

# create a database called TryDB
db = mongo_client['TryDB']

# Create collection if it doesn't exist
COLLECTION_NAME = "Try_Collection"

collection = db[COLLECTION_NAME]

if COLLECTION_NAME not in db.list_collection_names():
    # Creates a unsharded collection that uses the DBs shared throughput
    db.create_collection(COLLECTION_NAME)
    print("Created collection '{}'.n".format(COLLECTION_NAME))
else:
    print("Using collection: '{}'.n".format(COLLECTION_NAME))

This code block gives me below error:

ServerSelectionTimeoutError: c.service_name.mongocluster.cosmos.azure.com:10260: timed out (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms), Timeout: 30s, Topology Description: <TopologyDescription id: 627, topology_type: Unknown, servers: [<ServerDescription (‘c.service_name.mongocluster.cosmos.azure.com’, 1020) server_type: Unknown, rtt: None, error=NetworkTimeout(‘c.service_name.mongocluster.cosmos.azure.com:1020: timed out (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms)’)>]>
