I'm trying to use the pylast interface for the Last FM API on my flask web app, and it keeps giving me a ConnectionRefusedError, like this:

ConnectionRefusedError: [Errno 111] Connection refused

I'm using an ajax request for this, and I have flask_cors setup for this with @cross_origin on the appropriate function. The app works fine for me locally. The error's happening on this line when I instantiate the api's main class.

api = pylast.LastFMNetwork(api_key=API_KEY, api_secret=API_SECRET, username=username, password_hash=password_hash)

Can anyone tell me why I'm getting this error? As far as I know, the Last FM API is whitelisted. Does it have to do with it being an ajax request or the way I'm setting it up? Here is a link to the full pylast code, if that helps (the important part being the LastFMNetwork class): https://github.com/pylast/pylast/blob/master/src/pylast/init.py

I would really appreciate any help with this, since I was very close to getting this to work until I hit this snag. Thanks!

You might need to configure your package to use proxy. See https://help.pythonanywhere.com/pages/403ForbiddenError/

Thanks, using a proxy in pylast seems to have fixed my issue! Here's the relevant link for anyone else interested: https://github.com/pylast/pylast/issues/103
