403 Запрещенная ошибка на pgadmin4

Я следую учебному пособию здесь «Как установить и настроить pgAdmin 4 в режиме сервера» и все в порядке, только когда я вызываю в браузере IP своего сервера, я получаю ошибку 403 Forbbiten.

Мой /etc/apache2/sites-avaliable/pgadmin4.conf:

ServerName 1.1.2.1

WSGIDaemonProcess pgadmin processes=1 threads=25 python-home=/home/firm/environments/my_env
WSGIScriptAlias / /home/firm/environments/my_env/lib/python3.5/site-packages/pgadmin4/pgAdmin4.wsgi

<Directory "/home/firm/environments/my_env/lib/python3.5/site-packages/pgadmin4/">
    WSGIProcessGroup pgadmin
    WSGIApplicationGroup %{GLOBAL}
    Require all granted
</Directory>

И мой / etc / apache2 / apache2.conf:

ServerName localhost
