Firewall Service Restart

This is very urgent for me to get the information.
I did cAdvisor agent installation through a script that contains firewalld restart command on all docker swarm nodes via Ansible. After that, there was a network issue between Haproxy & Swarm Manager due to cAdvisor integration with all swarm nodes.

I did the same installation on docker servers and services was working fine on them. But in swarm I faced the issue that I mentioned above.

Is this mandatory to reboot the swarm nodes after firewall reload or restart?
Please let me know if this is a swarm issue or I am missing something?
