Hi, I was assigned a task to setup firewalld on all app servers. I was able to setup it in app server 1 and 2 but when I installed firewalld on app server 3, it won’t start. I tried removing firewalld and install it again but it didn’t work. Can you have look into it?
I tried Inderpreet’s suggestion but still status of firewalld is inactive dead. Also tried restarting the session about 5 times now but still no avail.

Inderpreet, sorry for the late reply and thanks for the link. After going back to the lab one more time, the problem somehow fixed itself and I was able to complete the labs.
