First Project and Hacked?

Thank you so much for pointing me in the correct links.

Now I’m trying to secure the server .

but I dont get why I only can work well with bindIp: 127.0.0.1, ipServer, VCPIp,

and also change the port , but this is not working at all i get always:

MongoDB shell version v4.0.3
connecting to: mongodb://127.0.0.1:27662/
2020-06-12T14:06:50.208-0500 E QUERY    [js] Error: couldn't connect to server 127.0.0.1:27662, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27662 :: caused by :: Connection refused :
connect@src/mongo/shell/mongo.js:257:13
@(connect):1:6
exception: connect failed

does my yaml config is wrong?
