What is the status of the firewalld service on your system?
Firewalld is a default firewall management software on RHEL 7 family.
Since I am an ubuntu user,the default firewall system for Ubuntu is ufw but you can install and use Firewalld if you prefer by running the commands
sudo apt-get install firewalld
By default, the service should be started, if not running, start and enable it to start on boot:
sudo systemctl enable firewalld
sudo systemctl start firewalld
Now to check the status of your firewalld service you can use the command
$ systemctl status firewalld
Again this is for UBUNTU
for RHEL-7,
to check the status you can use the same command
# systemctl status firewalld
