Linux Network Services Task failed

Hello,
I have failed Linux Network Services
even if I have stooped the process that was killed httpd service
Installed firewalld and added the proper port from the jump server I got a connection from stapp01 and could even curl to the page
Could you please tell me what did I do wrong?
Thanks

You need not install firewalld for this task. iptables is used for filtering. you can verify using
sudo iptables -L -v -n
and add specific rules to allow httpd.
