When I install firewalld on the app servers, it gets installed on all successfully. But on one of the app servers I see an error when I try to start the firewalld service. I have tried this multiple times but run into the same issue every time. Because of this, I am unable to configure firewall on that failed app server and hence unable to complete my task.
Anybody else faced the same issue? Any tips on how to workaround this issue?
