nodejs/express app can't serve on port 5000
I wonder if anyone have same problem with Ubuntu 14.04.
I am writing a backend nodejs/express app that listen to port 5000 and interact when receives http put/get request. The app starts and runs fine. but I cannot access that port from another computer. First I thought it was nginx problem but I can access the regular http 80 port.
I also check the ufw and Iptable, both are inactive(default setting). Domain name resolution also works fine.
Hope anyone with brighter mind can help.
