I believe there's 2 ways you could face this problem

1. Anti-virus or firewall blocking the MongoDB Reference
2. MongoDB is not deployed yet on the localhost:27017 OR choose to deploy it online instead to ease things up (offered by the official website, follow the steps and you will get the new mongo_url to be replaced). MongoDB installation
