SOLVED NTP No Server Suitable For Synchronization Found Centos

Question

I'm trying to set up an ntp server, and I can't query it. Whenever I try, I get this message:

 6 Mar 18:57:01 ntpdate[27050]: no server suitable for synchronization found

Here is my ntpd.conf file

# For more information about this file, see the man pages
# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).

driftfile /var/lib/ntp/drift

# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.

# Permit all access over the loopback interface.  This could
# be tightened as well, but to do so would effect some of
# the administrative functions.

So, it turns out my teacher who's server I was connecting to via ssh had a firewall up that was blocking ntp. He was using firewalld, and to solve this, I used these commands:

firewall-cmd --add-service=ntp --permanent firewall-cmd --reload

Check the status of your ntp server: systemctl status ntpd

If it's down: start the server up: service ntpd start
