I am trying to run a node app and am getting mongoerror failed to connect to server [IP] on first connect
How do I solve this? I want to have a separate database server than my web server. I have tried public and private IP’s and neither worked.
When I do mongod it shows the database is running so that it out.

By default, the MongoDB One-Click application is secured with a UFW-managed firewall. In order to allow your Node application to access the MongoDB instance, you must open a port in the firewall. This command will allow access from the Node app’s IP address and nowhere else:
- sudo ufw allow from node_ip_address to any port 27017
Additionally, MongoDB is configured to only listen on the local interface by default. To allow remote connections, modify the value of bindIp in /etc/mongod.conf If you do so, you are highly advised to first review the security checklist from the MongoDB documentation. In addition to enabling one of the forms of authentication supported by MongoDB.
The relevant section of the config file should look like:
# [ ... ]
net:
port: 27017
bindIp: 127.0.0.1,ip_of_mongo_droplet
# [ ... ]
