Looks like the network connection is working properly.

If the network connection is fine, verify that your DNS settings are configured correctly.

.. code-block:: bash

    $ cat /etc/resolv.conf
    nameserver 114.114.114.114
    nameserver 8.8.8.8

If the DNS settings are not configured correctly, you can try to configure them manually.

.. code-block:: bash

    $ sudo vim /etc/resolv.conf
    nameserver 114.114.114.114
    nameserver 8.8.8.8

> Make sure you include 8.8.8.8 as a nameserver as this is a public DNS server.

If the problem persists, please contact the data center technicians.
