Cloudinary

I`m having an error when using Cloudinary, the error is this:-

Unexpected error - MaxRetryError("HTTPSConnectionPool(host='api.cloudinary.com', port=443): Max retries exceeded with url: /v1_1/yaluwo/image/upload (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7fcc64186400>: Failed to establish a new connection: [Errno 111] Connection refused'))")

I followed the toturial django-cloudinary-storage in pypi

Can you support me with this, when I tried this offline with my code on the local pc it worked, but when I upload it online I get this error?

The connection refused error suggests that the library that you're using is not proxy-aware. Free accounts on PythonAnywhere have to access the external Internet via a proxy server. That's normally invisible to you -- we put the details of the proxy into the system environment, and most HTTP libraries like requests will see those details and will use the proxy automatically. However, if you're using a library that does not look for the proxy information, it will try to connect directly and will get an error like that.

What is the full stack trace that you're getting for that error? Perhaps there will be some clues in there as to how to configure the library to use a proxy.

It looks like you need to set api_proxy in an environment variable to get it to work -- this GitHub issue has the details.
