Hi there,

Cluster hostnames do not resolve using standard dig requests to the hostname in the connection string.

MongoDB clusters are hosted on multiple nodes and each has its own hostname. To retrieve the node hostnames of a cluster using dig, you must specify the srv record type in the request and prepend _mongodb._tcp. to the hostname in the connection string like this:

dig srv _mongodb._tcp.<cluster-hostname>

When you connect to your cluster, you need to make sure that you provide the +srv flag in the connection string as follows:

mongo "mongodb+srv://doadmin:<replace-with-your-password>" --tls

If you are still unable to connect, you might have locked down the database cluster to a specific set of IP addresses via the Trusted Sources. If this is the case, make sure to add your IP address to the Trusted Sources list as well.

Let me know how it goes!
