Permission Denied

[iDevo]

Hi there!
I started setting up PyFCM, with the given lines of code in the readme:

    push_service = FCMNotification(api_key="AAAAbMf....")
    registration_id = "emNeRG...."
    message_title = "Uber update"
    message_body = "Hi john, your customized news for today is ready"
    result = push_service.notify_single_device(registration_id=registration_id, message_title=message_title, message_body=message_body)
    print result

The problem is, that this produces a 500 Server Error with the following exception:

File "/Users/GamerXX/Documents/Party/lib/pyfcm/fcm.py", line 86, in notify_single_device
self.send_request([payload])
File "/Users/GamerXX/Documents/Party/lib/pyfcm/baseapi.py", line 174, in send_request
response = requests.post(self.FCM_END_POINT, headers=self.request_headers(), data=payload)
File "/Users/GamerXX/Documents/Party/lib/requests/api.py", line 110, in post
return request('post', url, data=data, json=json, **kwargs)
File "/Users/GamerXX/Documents/Party/lib/requests/api.py", line 56, in request
return session.request(method=method, url=url, **kwargs)
File "/Users/GamerXX/Documents/Party/lib/requests/sessions.py", line 488, in request
resp = self.send(prep, **send_kwargs)
File "/Users/GamerXX/Documents/Party/lib/requests/sessions.py", line 609, in send
r = adapter.send(request, **kwargs)
File "/Users/GamerXX/Documents/Party/lib/requests/adapters.py", line 473, in send
raise ConnectionError(err, request=request)
ConnectionError: ('Connection aborted.', error(13, 'Permission denied'))

I've also downgraded to version 1.2 because I red in another post, that this version might run smoother but that wasn't the trick.

When I'm using Postman to post the exact same content to FCM manually, the request is successful.

Does anyone might have an idea?
Thanks!

@iDevo that's more likely to be an issue with the requests library, I'll suggest you should try to upgrade the requests library

@olucurious thanks for your quick answer! I tried upgrading the requests library but it tells me, that it is already up to date:

pip install requests --upgrade
Requirement already up-to-date: requests in /Library/Python/2.7/site-packages

@iDevo are you using GAE? The issue has been referenced here: https://github.com/kennethreitz/requests/issues/3018

You should try:
pip uninstall requests (2.5.1)
pip install requests==2.3

Thank you so much @olucurious ! That downgrade did the trick!
