Task failed Firewalld

Hi Inderpreet,
I have successfully run and performed all task for firewalld, task is however failed stating "nginx service on app server 3 is not reachable. See screenshot, nginx is currently up and running on app server 3. Please assist.

Hv u verified connectivity to nginx after completion ?

how do you verify after adding the rules

with help of curl command.

like this curl -i ?
