</div>You should check at server side:<br>
<br>
1) if tftp service is enabled:<br>
# chkconfig --list tftp<br>
<br>
Note: This output shows SysV services only and does not include native<br>
systemd services. SysV configuration data might be overridden by native<br>
systemd configuration.<br>

2) if xinetd daemon is running (also "service xinetd status"):<br>
# systemctl status xinetd.service<br>
xinetd.service - LSB: start and stop xinetd<br>

3) /etc/hosts.allow (if You use hosts.allow/hosts.deny) should contain:<br>

4) if You use firewall (iptables), You should load nf_conntrack_tftp module,<br>
for tracking ephemeral ports. That means /etc/sysconfig/iptables-config should<br>
contain line as:<br>
...<br>
IPTABLES_MODULES="nf_conntrack_tftp"<br>
