Playframework - activator UI - connection refused when accessing from internet

Question

I have installed the playframework in digital ocean (Ubuntu) and installed activator UI. the UI is located at http:// 127.0.0.1:8888, however I cannot access this port from the internet. i.e. say my digitalocean server IP is 10.100.10.10, i cannot access http:// 10.100.10.10:8888 from my personal PC

however I can wget using localhost in the server, any idea how can I access this page from the internet?

wget http:// 127.0.0.1:8888

Answer 1

I found the solution, it is due to the service forced to listen 127.0.0.1, setting below can resolve and launch Activator on a WAN on port 80

./activator -Dhttp.address=0.0.0.0 -Dhttp.port=80
