Connection refused on custom port on Azure linux VM

Question

I have a linux vm on Azure. I opened an inbound rule for port 20212 tcp and furthermore in created a rule in iptables to allow traffic to this port.

But when i do telnet 127.0.0.1 20212 i get a connection refused error and also when i do telnet SERVER-IP 20212 i get the same error. Is there any other step in need in opening a custom port on Azure VMs

Please ensure your port 20212 is listening on `tcp`. You could use `netstat -ant|grep 20212`. The result shoud be like as below `tcp 0 0 0.0.0.0:20212 0.0.0.0:* LISTEN ` — Shui shengbao, Feb 03 '17 at 06:11
According to your description, I guess your app is not running. — Shui shengbao, Feb 03 '17 at 06:16

There are 3 moving pieces to this puzzle:

Network Security Group allowing a port
Linux VM firewall allowing a port
Application that is running and listening on the port

It appears that you are missing the third one.
