**3 points** are to be checked:

1. Check whether :file:`/etc/nginx/sites-enabled/wapt.conf` is a symbolic link of :file:`/etc/nginx/sites-available/wapt.conf`, using this command:

  .. code-block:: bash

    ls -l /etc/nginx/sites-enabled/wapt.conf

  * If the symbolic link exists, the output should be:

  .. code-block:: bash

    lrwxrwxrwx 1 root root 36 Jun 9 09:35 /etc/nginx/sites-enabled/wapt.conf --> /etc/nginx/sites-available/wapt.conf

  * If the symbolic link does not exist, then remove :file:`/etc/nginx/sites-enabled/wapt.conf` and create a new symbolic link:

  .. code-block:: bash

    rm /etc/nginx/sites-enabled/wapt.conf

    ln -s /etc/nginx/sites-available/wapt.conf /etc/nginx/sites-enabled/wapt.conf

2. Check whether the file :file:`licences.json` is present in :guilabel:`location` section of :file:`/etc/nginx/sites-enabled/wapt.conf`:

  .. code-block:: bash

    location ~ ^/(wapt/waptsetup-tis.exe|wapt/waptagent.exe|wapt/waptdeploy.exe|sync.json|rules.json|licences.json)$ {
            add_header Cache-Control "store, no-cache, must-revalidate, post-check=0, pre-check=0";
            add_header Pragma "no-cache";
            root "/var/www";
        }

  * If the :file:`licences.json` file exist, then restart :program:`Nginx`:

  .. code-block:: bash

    systemctl restart nginx

  * Then, add the :file:`licences.json` file in :guilabel:`location` section of :file:`/etc/nginx/sites-enabled/wapt.conf` and restart NGINX.

  .. code-block:: bash

    systemctl restart nginx

3. If you get an error, empty :file:`/var/www/licences.json`:

  .. code-block:: bash

    > /var/www/licences.json 

  * Then, retry :ref:`activating the WAPT licence <licence_activation>`.
