On CCM, attempting to apply the configuration, but got the following error,

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.

In the log, seeing the following error

OUTPUT=/usr/bin/wget --save-cookies nagiosql.cookies --keep-session-cookies http://localhost/nagiosxi/includes/components/ccm/ --no-check-certificate --post-data 'submit=Login&hidelog=true&loginSubmitted=true&backend=1&username=nagiosxi&password=xxxxxxxxxx' -O nagiosql.loginNAGIOSQL LOGIN FAILED!
RETURNCODE=2

Any hints ?

Are you using a proxy? If so, please run through https://support.nagios.com/kb/article.php?id=147

Are you using an offline db? Any other customizations, like changing the db password? If you changed the db password or name, you'll need to also change that in your /usr/local/nagiosxi/html/includes/components/ccm/config.inc.php. You'll also need to change it in /usr/local/nagiosxi/html/config.inc.php, but the more immediate issue is with the CCM.

Also, what version of XI is this? On what OS/version are you running XI?

Yes. The instructions were followed. The accesses to the local http are fine.

Here's a logout while the CCM conf being applied.

No customization. No DB account nor config were changed. The only thing that was changed was the login password for nagisadmin account.

Running XI 5.4.2 on Redhat 5.11

Please follow this KB article:
If that doesn't resolve it, go to Admin > System Config > Reset Security Credentials
- Don't change anything, just click the Update Credentials button.

Now test it again.

If you are still having issues, please go to Configure > Core Config Manager > Config Manager Admin > Manage Config Access
- Edit the nagiosxi user, type in the password that the previous error showed (taken from the URL listed in the tail output you posted) and click the Save button


Try the upgrade again, if you are still having issues, please run this command and sent the full output:
- Make sure to change PASSWORD in the command below
Thank you

Awesome. Update Credentials and the issue is resolved. Thank you.

As your issue is resolved, I am going to go ahead and lock this thread.
