Can't access my droplet's website via IP address

I can ssh to my droplet’s IP address and git clone, git pull to get my code from github.

After I run “node stringserver” in my droplet, I did see the console log and in another terminal of my droplet, I can see the http output using curl.

• root@nodejsAssignments:~/assignment1-tucisf# node stringserver Server running at http://localhost:8080/

• root@nodejsAssignments:~# curl http://localhost:8080 Hello World

However, when I go to chrome, using the IP address to access my droplet web server, I get

"This site can’t be reached xxx.xxx.xxx.xx refused to connect. Try:

Checking the connection Checking the proxy and the firewall ERR_CONNECTION_REFUSED"

To make sure my digital ocean’s droplet is really not reachable as a web server, I tried IE, Firefox, and curl from my own machine, all got the same error: the site “refused to connect”

Please help, Thanks, Suefen
