The code below, it shows the download url in the response but if I try to download from the Download button, it has {"error_code":31326,"error_msg":"user is not authorized, hitcode:109","request_id":347419335550786427}. But, If I copy the same download URL and paste on a browser URL , it gets downloaded.

Code:

`@app.route(‘/convert’, methods=[‘POST’])
def convert():
try:
app.logger.debug(“Received form data: %s”, request.form)

    # Load cookies and headers from the file
    cookies, headers = load_cookies_and_headers()

    # Get the initial URL from the form data
    url1 = request.form['terabox_url']
    app.logger.debug(f"Initial URL: {url1}")

    # Use a new requests session for making HTTP requests
    with requests.Session() as session:
        # Follow redirects manually to get the final URL
        response1 = session.get(url1, cookies=cookies, headers=headers, allow_redirects=False)
        while response1.is_redirect:
            url1 = response1.headers['Location']
            app.logger.debug(f"Redirected to URL: {url1}")
            response1 = session.get(url1, cookies=cookies, headers=headers, allow_redirects=False)

        response1.raise_for_status()
        app.logger.debug(f"Response 1 status code: {response1.status_code}")

        jsToken = extract_js_token(response1.text)
        app.logger.debug(f"Extracted jsToken: {jsToken}")

        if jsToken:
            parsed_url = urllib.parse.urlparse(url1)
            query_params = urllib.parse.parse_qs(parsed_url.query)
            surl = query_params.get('surl', [None])[0]
            app.logger.debug(f"Extracted surl: {surl}")

            if surl:
                url2 = f'https://www.1024tera.com/share/list?app_id=&web=1&channel=dubox&clienttype=0&jsToken={jsToken}&dp-logid=&page=1&num=20&by=name&order=asc&site_referer=&shorturl={surl}&root=1'

                response2 = session.get(url2, headers=headers, cookies=cookies)
                response2.raise_for_status()
                app.logger.debug(f"Response 2 status code: {response2.status_code}")

                json_response = response2.json()
                app.logger.debug(f"JSON response: {json.dumps(json_response, indent=4)}")

                if json_response and json_response.get('errno') == 0:
                    list_item = json_response['list'][0]
                    download_url = list_item['dlink']
                    streaming_url = f'https://www.1024tera.com/share/streaming?uk={json_response["uk"]}&shareid={json_response["share_id"]}&type=M3U8_FLV_264_480&fid={list_item["fs_id"]}&sign={list_item["md5"]}&timestamp={json_response["server_time"]}&esl=1&isplayer=1&ehps=1&clienttype=0&app_id=250528&web=1&channel=dubox'

                    return jsonify({
                        'download_url': download_url,
                        'streaming_url': streaming_url,
                        'thumbnail_url': thumbnail_url,

                    })

            return jsonify({'error': 'Failed to extract jsToken.'}), 400

except Exception as e:
    app.logger.exception("Exception occurred")
    return jsonify({'error': str(e)}), 500`

I have tried using flask session, but for small size files, it gets downloaded but for bigger size files, it takes much time to load the download , also the file is not downloaded, instead it gets downloaded as download.htm but autoblocked too.
