I get the following message when clicking apply configuration.

Backend login to the Core Config Manager failed.

An error occurred while attempting to apply your configuration to Nagios Core.
Monitoring engine configuration files have been rolled back to their last known good checkpoint.

I have tried

Code: Select all

su nagios
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh

Hi

Please try the following on the CLI of the Nagios server:

Code: Select all

chage -l nagios
 su - nagios
 cd /usr/local/nagiosxi/scripts
 time ./reconfigure_nagios.sh

This should show what is causing the Backend login error.
See the https://support.nagios.com/kb/article/n ... s-780.html KB article for possible resolution.

Thank you!
