'Cloudinary: Failed to establish a new connection: [Errno 111]

I am trying to upload a file with Python -not Django- across Cloudinary API but I am getting "Failed to establish a new connection: [Errno 111]". I am executing this script in PythonAnywhere.

This is my code:

import cloudinary
from cloudinary.uploader import upload
from cloudinary.utils import cloudinary_url

cloudinary.config(
  cloud_name = "name",
  api_key = "API_KEY",
  api_secret = "API_SECURE",
  secure = True
)

upload("BookCoverTest.jpg")

And the error I am getting is this one:

Traceback (most recent call last):
  File "/home/gcancino/notionBooks.py", line 148, in <module>
    queryWithFilter()
  File "/home/gcancino/notionBooks.py", line 71, in queryWithFilter
    getBookDataFromAPI(namee, pID)
  File "/home/gcancino/notionBooks.py", line 93, in getBookDataFromAPI
    upload("RitesofLucifer.jpg")

    raise err

    sock.connect(sa)

During handling of the above exception, another exception occurred:

e/image/upload (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f7eb1283280>: Failed to establish a new connection:  [Errno 111] Connection refused'))

I have tried as well to configure this but don't know what to put in proxy (execute that code in the bash console of PythonAnywhere)

export CLOUDINARY_URL=cloudinary://API_KEY:API_SECRET@DB?api_proxy=DONTKNOWWHATTOPUTHERE

If you're using a free account on PythonAnyhwere, you have a restricted internet access to whitelisted domains, see whitelist. If the endpoint you're trying connect to is a public API, you can request a whitelist addition by contacting PA stuff and providing links to official docuementation of the given API endpoint.
