问题
I changed bindIp setting to
bindIp: 127.0.0.1, 0.0.0.0
in mongod.conf on my ubuntu server hosted on Linode and restarted mongod and status looks ok.
I opened mongodb port on ufw
sudo ufw status Status: active
To Action From -- ------ ---- 22/tcp ALLOW Anywhere 10000
ALLOW Anywhere Nginx Full
ALLOW Anywhere 3333
ALLOW Anywhere 27017

ALLOW Anywhere (v6) Nginx Full (v6)
ALLOW Anywhere (v6) 3333 (v6)
ALLOW Anywhere (v6) 27017 (v6)
ALLOW Anywhere (v6)
Connecting to it from my mac throws error:
mongo mongodb://admin:secret@ubuntuipaddress/fielddb?authSource=admin MongoDB shell version v3.6.2 connecting to: mongodb://ubuntuipaddress/fielddb?authSource=admin 2018-04-08T13:47:32.212 W NETWORK [thread1] Failed to connect to ubuntuipaddress:27017, in(checking socket for error after poll), reason: Connection refused 2018-04-08T13:47:32.214 E QUERY

How to fix this issue?
回答1:
Disable your firewall and try to see if you can connect, if you can then it's your fw rules. Try this first to see if this helps.
回答2:
The problem was wrong setting of bindIP in mmongod.conf. Changing to:
bindIp: 127.0.0.1,ip_address_of_host_running_mondgod
fixed the problem. Replace ip_address_of_host_running_mondgod with ip address of host running mongod like 137.142.177.4
