Fix MongoNetworkError

✅ Solution

MongoNetworkError often arises when Payload CMS can't resolve the MongoDB connection string's hostname, usually due to a typo, DNS issue, or the database not being publicly accessible. Double-check your `MONGODB_URI` environment variable for accuracy, ensure your database is reachable from the Payload CMS server (firewall rules, VPC peering), and confirm DNS resolution is functioning correctly in your hosting environment.
