im writed simple flask server-client app. and put it on dedicated server, but flask starts gives empty responses after 1 min. But in logs all is ok and gives 200 code.
and there is it response: server response

here is server code:

@app.route('/login', methods=['POST'])
def login():
    if request.remote_addr not in blocked_ips:
        data = request.json
        password = data['password']
        hwid = data['hwid']
        hashed_input_password = hash_builder(password)

        try:
            with db.connection.cursor() as cursor:
                sql = "SELECT hwid FROM users WHERE license = %s"
                cursor.execute(sql, (hashed_input_password,))
                result = cursor.fetchone()
                if result:
                    db_hwid = result['hwid']
                    if db_hwid is None:
                        return jsonify({'status': 'success', 'message': 'HWID not set', 'hwid': hwid})
                    elif db_hwid == hwid:
                        return jsonify({'status': 'success', 'message': 'Login successful'})
                    else:
                        return jsonify({'status': 'failure', 'message': 'Invalid hardware ID'})
                else:
                    return jsonify({'status': 'failure', 'message': 'Invalid key'})
        except Exception as e:
            return jsonify({'status': 'error', 'message': str(e)})

But server is still running after that without errors. Client is made with requests and just checking server responses so i dont think its needed

idk what can i do, i just want that this server script runs forever without that shit 🙁
