SSL handshake mongodb fail

1

I’m deploying Flask app via Web Service.
And need to use MongoDB as database.

Locally it works
But when on Render, it throws error:

"error": "SSL handshake failed: ac-zic2axe-shard-00-01.n3bexs7.mongodb.net:27017: [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:1006) (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms),SSL handshake failed: ac-zic2axe-shard-00-00.n3bexs7.mongodb.net:27017: [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:1006) (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms),SSL handshake failed: ac-zic2axe-shard-00-02.n3bexs7.mongodb.net:27017: [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:1006) (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms), Timeout: 30s, Topology Description: <TopologyDescription id: 663f390406f39995264645ac, topology_type: ReplicaSetNoPrimary, servers: [<ServerDescription ('ac-zic2axe-shard-00-00.n3bexs7.mongodb.net', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('SSL handshake failed: ac-zic2axe-shard-00-00.n3bexs7.mongodb.net:27017: [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:1006) (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms)')>, <ServerDescription ('ac-zic2axe-shard-00-01.n3bexs7.mongodb.net', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('SSL handshake failed: ac-zic2axe-shard-00-01.n3bexs7.mongodb.net:27017: [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:1006) (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms)')>, <ServerDescription ('ac-zic2axe-shard-00-02.n3bexs7.mongodb.net', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('SSL handshake failed: ac-zic2axe-shard-00-02.n3bexs7.mongodb.net:27017: [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:1006) (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms)')>]>"

I’ve set secret env in settings in Render, and locally I have it in .env
I also have it in docker, but not sure how to put those secret env in Docker in Render.



from pymongo.mongo_client import MongoClient
from pymongo.server_api import ServerApi


import os
from dotenv import load_dotenv, dotenv_values 
load_dotenv() 

# Render docs says I need to use: environ ? 
password = os.environ.get("PASSWORD_MONGODB") or os.getenv("PASSWORD_MONGODB") 
username =  os.environ.get("USERNAME_MONGODB") or os.getenv("USERNAME_MONGODB")



uri = f"mongodb+srv://{username}:{password}@cluster0.n3bexs7.mongodb.net/?retryWrites=true&w=majority&appName=Cluster0"

# Create a new client and connect to the server
client = MongoClient(uri, server_api=ServerApi('1'))

I needed to enable MongoDB connection from all IP hosts. In “network” tab…

Hi,

I replied to the ticket you also opened, I’ll repeat my response:

You likely need to allowlist the Render outbound IP with your MongoDB provider. Render outbound IPs and how to find them are covered in the docs here: https://docs.render.com/static-outbound-ip-addresses

Your community post shows you have opened your DB up to all IPs, you may want to restrict that to only the required IPs.
