Task failed due to firewalld not starting

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?

@zahid You could try this

systemctl restart dbus
systemctl restart firewalld

Thanks Inderpreet. That’s very unfortunate for me that I didn’t know this and it’s costing me half of the points.

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.

Anyone has any other suggestions?

Thanks in advance


run the status command with -l
sudo systemctl status firewalld -l for more details and share the output.

Check this if helps


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.

But nevertheless thanks again for your help
