Linux Network Services : Task completed but marked Failed

Hi @Inderpreet
I have performed this task and get everything work but the task status failed. here is the specified error - Seem’s like you have stopped iptables firewall service on App Server 1
As you can see in the task description there is no guideline specifying tu use iptables or firewalld. In my case, I used firewalld .
Can you check please?
