Adding new IP address in mongod.conf in bindIp doesn't work
Ubuntu: 20.04
MongoDB: 4.4.1
I was following this tutorial (https://www.digitalocean.com/community/tutorials/how-to-configure-remote-access-for-mongodb-on-ubuntu-20-04) and I have a problem with adding new IP address in the bindIp property.
I tried same thing as it is in the tutorial but it doesn’t work:
net:
port: 27017
bindIp: 127.0.0.1,there_is_my_ip
I was looking for the answer and trying other options like [127.0.0.1,there_is_my_ip] or "127.0.0.1,there_is_my_ip" but none of these work for me.
After adding new IP with any of these options my MongoDB server fails to start.
What should I do?

Same behavior for me, as experienced by @PtakWarsawExpo. Another relevant detail may be that after adding any ip address to the mongodb.conf file’s net/bindIp parameter, I’m unable to log into mongo at all, even from the same server (127.0.0.1).
so in mongod.conf:
net:
port: 27017
bindIp: 127.0.0.1
mongo -u myadminusername -p –authenticationDatabase admin
MongoDB shell version v4.4.2
Enter password:
connecting to: mongodb://127.0.0.1:27017/?authSource=admin&compressors=disabled&
gssapiServiceName=mongodb
Implicit session: session { “id” : UUID(“6623b41d-699e-4d0b-b088-940b0528957a”)
}
MongoDB server version: 4.4.2
But when the net/bindIp config is changed:
net:
port: 27017
bindIp: 127.0.0.1,my.remote.ip.addr
mongo -u myadminusername -p –authenticationDatabase admin
MongoDB shell version v4.4.2
Enter password:
connecting to: mongodb://127.0.0.1:27017/?authSource=admin&compressors=disabled&
gssapiServiceName=mongodb
Error: couldn’t connect to server 127.0.0.1:27017, connection attempt failed: So

After removing the remote ip address from mongodb.conf’s net/bindIp, I can log back in to mongo, on the mongodb server.
Ok, so I struggled with this for way too long.
My problem was I thought I was supposed to “bindIp” of the connecting device. Nope, I misunderstood, when I instead bindIp of the mongo-droplet public IP everything worked just fine.
Also, do not believe other statements on internet about formatting the IP list as a string using “” or a array using []. This tutorial is correct, just comma-separated is the way to go if your'e using mongo 4.4! (haven’t tested with spaces though)
Hopes this saves time for someone :)
