Lab - Remove and Re-Add a Node -- Problem

–I’ve pinged m103.mongodb.university and the IP address 127.0.1.1

–I’ve added to the /etc/hosts file:
127.0.1.1 m103.mongodb.university

–I’ve removed the 3rd set:
rs.remove(“192.168.103.100:27003”)

–I’ve readded the set:
rs.add(“m103.mongodb.university:27003”)

I keep getting a “connection” refused error message.

Can someone please tell me what I’m doing wrong?

Thank you.

Never mind. I did it the wrong way. It’s a lot easier than I made it out to be.
Don’t use ping.
127.0.0.1 m103
