Connection Error - POST request

I am trying to send data from an outside computer via a POST request. I get the following error client side.

requests.exceptions.ConnectionError: ('Connection aborted.', OSError(0, 'Error'))

#Client side code
import requests
data = {}
url = 'https://www.prestoscore.com'
x = requests.post(url, data)
print(x.text)



#Python anywhere code
@application.route('/', methods=['GET', 'POST'])
def data():
    if request.method == 'POST':
        data = request.json
         print(data)


        return render_template('index.html')

What do you see in your error log? (link to logs are available on the "Web" page on PythonAnywhere).

Nothing appears in the error or server log. That leads me to believe its a client side problem however if I send the request to any other url i get a response instead of an error which leads me to believe its a server issue

Interesting- I tried again and got a more clear SSL error, tried again just now and got the received text that i have setup so it works properly... .strange

Have you tried to access it form the other machine (from different network location)?
