Virtual Hosts apache ERR_CONNECTION_REFUSED

Could someone help me? I set up a virtualhost in Apache so that when I entered the address testsystem I was taken to the homepage of my system designed in laravel, but when I entered to this address the browser gives me the message that the website can not be accessed. The www.testsistema.com page rejected the connection. ERR_CONNECTION_REFUSED, but when entering www.testsistema.com:8000 it shows me the main page of xampp. My httpd-vhost file is configured as follows

<VirtualHost *:8000>
  DocumentRoot "C:/xampp/htdocs"
  ServerName localhost:8000
</VirtualHost>

<VirtualHost *:8000>
  DocumentRoot "C:/web/Sistema/public"
  ServerName www.testsistema.com
  <Directory "C:/web/Sistema/public"
    Require all granted
  </Directory>
</VirtualHost>

My httpd file is as follows:

#
# MaxRanges: Maximum number of Ranges in a request before
# returning the entire resource, or one of the special
# values 'default', 'none' or 'unlimited'.
# Default setting is to accept 200 Ranges.
#MaxRanges unlimited

#
# EnableMMAP and EnableSendfile: On systems that support it, 
# memory-mapping or the sendfile syscall may be used to deliver
# files.  This usually improves server performance, but must
# be turned off when serving from networked-mounted 
# filesystems or if support for these functions is otherwise
# broken on your system.
# Defaults: EnableMMAP On, EnableSendfile Off
#
#EnableMMAP off
#EnableSendfile off

and my windows hosts file as follows:

127.0.0.1       localhost
::1             localhost

127.0.0.1 www.testsistema.com

Does anyone know if there is something that I need to configure or something I'm doing wrong?
