Name or service not known

When executing your code I get an error.

I execute the following code:

        from OpenKVK import ApiClient

        client = ApiClient()
        client.get_by_city('Rotterdam')

Which Results in the following error:

Traceback (most recent call last):
  File "/kvk/contacts/tests.py", line 11, in test_get_by_dossier
    client.get_by_city('Rotterdam')
  File "/kvk/venv/lib/python3.6/site-packages/OpenKVK/Client.py", line 291, in get_by_city
    return self.do_query(basequery,limit,**kwargs)

    '_open', req)

    raise URLError(err)
urllib.error.URLError: <urlopen error [Errno -2] Name or service not known>

Can anyone help me to resolve this error?

I get the same error. It seems that this module is using some outdated API. In Client.py I find a BASE_URL which points to http://api.openkvk.nl. This URL does not exist at all.
I did find another API with a similar name: https://api.overheid.io/openkvk (found at https://overheid.io/documentatie/openkvk). There is also an https://openkvk.nl address which does not work at the moment because their SSL certificate expired 2 days ago.
