What is the name of the host?

Also, please provide the output of the following:
# date
# hwclock
# grep date.timezone /etc/php.ini
# mysql -unagiosxi -pn@gweb -e "SELECT NOW();"
# service ntpd status
# df -i
# df -h

Regarding the instructions below, if you do not have killall, you can install it via the following command:
# yum install psmisc

If psmisc is not in your repos, then instead you can check to make sure nagios is not running with
# ps -aef | grep nagios

If that document does not resolve your issue, please run the following commands in order and report any errors. You ***must*** use mariadb instead of mysqld in the commands below, ***if*** you have mariadb.
# service nagios stop
# service ndo2db stop
# service mysqld stop
# service crond stop
# service httpd stop
# killall -9 nagios
# killall -9 ndo2db
# rm -rf /usr/local/nagios/var/rw/nagios.cmd
# rm -rf /usr/local/nagios/var/nagios.lock
# rm -f /usr/local/nagios/var/ndo.sock
# rm -f /usr/local/nagios/var/ndo2db.lock
# rm -f /usr/local/nagiosxi/var/reconfigure_nagios.lock
# for i in `ipcs -q | grep nagios |awk '{print $2}'`; do ipcrm -q $i; done
# service ndo2db start
# service nagios start
# service mysqld start
# service crond start
# service httpd start

Also, can you post a screenshot of http://YOURSERVER/nagiosxi/admin/globalconfig.php

I tried running through command steps outlined to restart/clear out lock files but still not working. This is strange that issue is only with this particular host. I have tried to re-add the host but it still did not work. What exactly is the host check attempting to do? ICMP poll ? Below is the output of the commands requested I run:

# date
Wed Jun 7 20:02:03 GMT 2017

# hwclock
Wed 07 Jun 2017 08:02:06 PM GMT -0.677835 seconds

# grep date.timezone /etc/php.ini
; http://www.php.net/manual/en/datetime.c ... e.timezone
date.timezone = Africa/Monrovia

# mysql -unagiosxi -pn@gweb -e "SELECT NOW();"
