Nagios XI HTTPS Issue

Hello,
Could you help on trouble shooting?
I followed
https://assets.nagios.com/downloads/nag ... s%20XI.pdf, to setup HTTPS for my newly installed Nagios XI. However, the
https://nagiosxi.connectedcarhub.com/ page looks strange and
https://nagiosxi.connectedcarhub.com/nagiosxi/ return 403 Forbidden. (
http://nagiosxi.connectedcarhub.com/nagiosxi/ works as expected).
The /var/log/httpd/error_log have record as below:

#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used. If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.

# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so

# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.

# Redirect permanent /foo http://www.example.com/bar

# Example:
# Alias /webpath /full/filesystem/path

Looks all right.
Output of this command?
Code: Select all
grep use_https /usr/local/nagiosxi/html/config.inc.php
Can you check your program URLs?

It needs to be set to true.
Also, in the document you linked, there is a section called "Forcing SSL with a Permanent Redirect".
I think you should read through the document again, it's likely you missed some steps.

I did not go through all the steps

- stopped on restart httpd.
Now after went through all the steps, it became worse:
http://nagiosxi.connectedcarhub.com/nagiosxi/ return 403. I tried to roll back to HTTP, by restore the original config files but failed (web UI is not accessible). Any instruction on rollback from HTTPS to HTTP?
What is the right command to restart the service?
Code: Select all
service nagiosxi restart
service nagios restart

You also should change your program URLs inside of XI.
