Nagios Support Forum

In /etc/httpd/conf.d/nagiosxi.conf are you forcing a redirect?

Yes, according to the manual - https://assets.nagios.com/downloads/nag ... s%20XI.pdf
I have redirect:
Redirect permanent / https://<Your-XI-Server-Address-or-Hostname>

Can you change

Redirect permanent / https://<Your-XI-Server-Address-or-Hostname>

to

Redirect permanent / https://<Your-XI-Server-Address-or-Hostname>/

And give it a whirl?

Thanks.

Hello, tryied, but with no result.

Lets try and run the reconfigure script as the nagios user and see if we get any errors that could help on this issue.
Run the following in a shell and post the output here.

Hello,

Done, log attached. There are some warnings, maybe that causes the problem.

The warnings are not causing the issue.
Can you post all of the files in this folder? Also, can you post the /etc/sudoers file?

Hello.

Your /etc/sudoers file seems to be missing some entries. Can you update it to the included settings below and see if that resolves the issue?

Added missing lines but with no effect (((.
