Question

ping: cannot resolve http://haltamah.app: Unknown host

Hello… I deployed a nodejs application with nginx server.

when I open the browser to the server’s ip http://159.89.55.168 I can see the app running

However, when I open it with my domain name http://haltamah.app I get the following error

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

When I run the following command curl http://haltamah.app I can see the app content

When I ping it ping http://haltamah.app I get the following error

‘ping: cannot resolve http://haltamah.app: Unknown host’

Any idea what could be the issue?

Hi there @ahmadmjh,

You can not ping over HTTP as ping uses ICMP rather than HTTP.

To avoid that error, you have to remove the http:// part of the FQDN as follows:

ping haltamah.app

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

Hope that this helps! Regards, Bobby
