Pythonanywhere - ConnectionRefusedError: [Errno 111]

Question

Here I have a model called User. It has 2 fields "Name" and "Phone". I am trying to authenticate with an OTP. Actually the code works fine on the local server. For this reason, I hosted the project on Pythonanywhere, but now it's getting an error on the server ConnectionRefusedError: [Errno 111] Connection refused

Essentials

Below is the code for the OTP message to send

def generate_otp(user, name, phone):
    otp = users.models.User.objects.make_random_password(length=4, allowed_chars='123456789')

    if not users.models.VerifyToken.objects.filter(user=user).exists():
        users.models.VerifyToken.objects.create(user=user, otp=otp, name=name, phone=phone)
        send_verification_message(phone, otp)
    else:
        token = users.models.VerifyToken.objects.get(user=user)
        token.otp = otp
        token.name = name
        token.phone = phone
        send_verification_message(phone, otp)
        token.save()
    return otp

def send_verification_message(phone, otp):
    phone = phone[3:14]
    conn = http.client.HTTPSConnection("api.msg91.com")
    payload = "{ \"sender\": \"BMyDay\", \"route\": \"4\", \"country\": \"91\", \"sms\": [ { \"message\": \"" + "Your verification code is " + otp + ".\", \"to\": [ \"" + phone + "\" ] } ] }"
    print(payload)
    headers = {
        'authkey': "xxxxxxxxxxxxxxxxxxx",
        'content-type': "application/json"
    }

    conn.request("POST", "/api/v2/sendsms", payload, headers)

    res = conn.getresponse()
    data = res.read()

    print(data.decode("utf-8"))
    return True

View

This is my view

class AuthAPIView(APIView):
    queryset = User.objects.all()
    lookup_field = "phone"
    permission_classes = [AllowAny]

    # Get OTP
    def put(self, request):
        name = request.data.get('name')
        phone = request.data.get('phone')

        if name and phone and phonenumbers.is_valid_number(
                phonenumbers.parse(request.data.get('phone'), 'IN')):
            # if user is exists
            if VerifyToken.objects.filter(phone=phone).exists():
                user = VerifyToken.objects.get(phone=phone).user
                generate_otp(user, name, phone)
            elif User.objects.filter(phone=phone).exists():
                user = User.objects.get(phone=phone)
                generate_otp(user, name, phone)
            else:
                username = User.objects.make_random_password(length=10)
                user = User.objects.create_user(username=username, phone=phone)
                generate_otp(user, name, phone)

            return Response({'response': 'OTP send to your mobile number: ' + str(phone), "user": user.id},
                            status=status.HTTP_200_OK)

        else:
            return Response({'response': 'Enter a valid data'}, status=status.HTTP_400_BAD_REQUEST)

Can someone help me with this?

You're probably on a free account that needs to access the internet through our proxy, but I don't see anywhere that you have configured your http library to use the proxy. Some libraries (like requests) use the proxy settings automatically and others do not. Search the PythonAnywhere help pages for "proxy" to find the proxy details and configure your http library to use them.
