在 flask 应用程序中出现 403 禁止错误

Question

I am running a flask application in AWS fargate. In the app, I call a POST api which internally needs to call a public endpoint to collect some data using requests.get() method.

@app.route("/findByPin", methods=["POST"]
def find_by_pin():
    pincode = request.form['pincode']
    headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}
    url = [SOME_URL]?pincode=pincode
    requests.get(url, headers=headers)

The error that I am facing is that the API call to the public endpoint is returning 403 status code in response. While if I run the application in my localhost, it works fine.

Since this is an open endpoint, I don't understand why it would return a 403 Forbidden error.

Edit: This is the error message: Request blocked. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner. Request blocked. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error.

The 403 error comes from the public endpoint you are calling, they might be blocking AWS IPs to prevent trafic overload from bots. You can tunnel your request trough a VPN running on a non AWS instance.
