. It looks like this is a MongoDB Atlas cluster. Please ensure that your Network Access List allows connections from your IP.To solve this, go to the dashboard and find Database & Network Access > IP Access List, then add your IP address. Be careful not to enter 0.0.0.0/0 as that will allow all IP addresses access to the cluster.
