Question

can not visit the web app made of angular cli on the digitalocean

I have built a simple web app using angular-cli 2,it works well in the local machine. now i tried to deploy it onto a digitalocean server,enter image description here

however when going to the web server link with http://ip address:4200, i can’t visit the web app.

Note: I can make sure the firewall is open to the web application on that port since in ufw status shows 4200 ALLOW Anywhere

no, there is no specific error on both web browser side or server side. On the web browser side, it just show me ‘This site can’t be reached, refused to connect.’

You need your local computer to connect to the server via ssh tunneling. ssh -L 4200:yourdigitaloceanipaddress:4200 user@yourdigitaloceanipaddress and then ng -serve host=0.0.0.0

Are you receiving any specific error when navigating to the URI (either in-browser or from the CLI)?
