Hi everyone,
I'm having trouble connecting to the mongodb from one of my web app. It used to work perfectly until a private endpoint was configured. I tried to replace the domain name in the connection string with the FQDN. I got this "pymongo.errors.ServerSelectionTimeoutError" error message.
Anyone can help please?

- Have you configured separate DNS settings, often configured via private DNS zones, which are required to connect to database when connecting through private endpoint
- What is your private endpoint connection status is showing , you can check that in networking of Cosmos DB under Privat endpoint connection. something like this

- I think I have already configured a customer DNS, and I can see the FQDN and IP addresses
- Yes I have double checked the status of endpoint is approved.

This issue might occur when the cluster does not have the correct firewall rule(s) enabled.
If you're trying to access the cluster from a non-Azure IP range, you need to add extra firewall rules.
Refer to Security options and features - Azure Cosmos DB for MongoDB vCore for detailed steps.
Firewall rules can be configured in the portal's Networking setting for the cluster.
Options include adding a known IP address/range or enabling public IP access.
Also, suggest you to verify that the network security group rules are configured correctly. You can check the NSG rules in the Azure portal under the "Networking" section of your MongoDB resource.
Double check the connection string settings are correct. You can check the connection string in your web app's configuration settings to ensure that it is using the correct FQDN and port number.
Also try connecting to the MongoDB server from a different machine to see if the issue is specific to your web app.
Please let us know.
