Traceback error when using urllib / BeautifulSoup. <urlopen error [Errno 11001] getaddrinfo failed>

Question

I can run the below code fine on my MacBook at home, but when running the same code at work I get a traceback error. I think the issue may be a network issue but I'm not 100% sure so wanted to share the code and traceback here to see if a more experienced individual may be able to confirm or have a better idea of what is going wrong! (the same sort of error come up when I try to use the googlesearch-python library as well).

I am trying to run the following code:

import urllib.request, urllib.parse, urllib.error
from bs4 import BeautifulSoup
import ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

url = 'http://py4e-data.dr-chuck.net/known_by_Ann.com'

x=0
while x <7:
    x +=1

    html = urllib.request.urlopen(url, context=ctx).read()
    soup = BeautifulSoup(html, 'html.parser')

    tags = soup('a')
    url = tags[17].get('href', None)
    print('Retrieving:',url)
print(tags[17].contents[0])

And I get the following error:

Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\lib\urllib\request.py", line 1354, in do_open
    h.request(req.get_method(), req.selector, req.data, headers,

    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 11001] getaddrinfo failed

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    raise URLError(err)

I am running the code as a test to see if I can pull hyperlinks from a webpage and then go into those said hyperlinks.

The code failed with the above mentioned traceback - I think it may be a network / internet connection issues. (I am trying to run the code at work - when done at home on my personal laptop it works fine).
