I can access mongo-express
I can connect via mongo3t using the following directly to 30000, or 30001
When I connect programmatically through my app using mongoose via mongodb://localhost:30000/ttt uri, I have no issue.
The problem comes when I try to connect using mongodb://localhost:30000,localhost:30001,localhost:30002/ttt?replicaSet=rs0, it will complain this. Either connect through mongo3t or via mongoose doesn’t work
[2020-08-29 22:29:44] [error] Could not connect to any servers in your MongoDB Atlas cluster. One common reason is that you're trying to access the database from an IP that isn't whitelisted.

I’m not sure why it is complaining about the MongoDB Atlas cluster though. I’m running this locally on my machine
Thanks!
