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)?
