Nagios core GUI/UI fails to open after nagios-4.4.6-4 to 4.4.9-1 update on Rhel8 vm.

Whoops! Error: Could not read host and service status information!

Nothing in /var/log/nagios/nagios.log.

/sbin/nagios -v /etc/nagios/nagios.cfg doesn't report any errors.

cgi.cfg exist in the same directory as nagios.cfg. After update paths have not changed.

Have you thought about checking the web server httpd?
The nagios service runs checks. The web server serves the web pages.
