ping: cannot resolve Unknown host

Hello… I deployed a nodejs application with nginx server.

when I open the browser to the server’s ip I can see the app running

However, when I open it with my domain name I get the following error

‘This site can’t be reached refused to connect.’

When I run the following command curl I can see the app content

When I ping it ping I get the following error

‘ping: cannot resolve Unknown host’

Any idea what could be the issue?

I’ve tested it and it seems to be working as expected.

Hope that this helps! Regards, Bobby
