Audio error when using InlineQueryResultAudio?

Question

Python

There is a code that uses a regular expression to catch a link to a track from the site.

URL = 'https://ruv.hotmo.org/search?q='
HEADERS = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:71.0) Gecko/20100101 Firefox/71.0', 'accept': '*/*'}

@bot.inline_handler(lambda query: len(query.query) > 0)
def query_text(query):
    try:
        vvod = re.search(r'(.+)', query.query)
    except AttributeError as ex:
        return
    vvod = vvod.group(1)
    try:
        html = requests.get(URL+vvod, headers=HEADERS)
        if html.status_code == 200:
            track = re.search(r'href="(.+)" class="track__download-btn"', html.text)
            executor = re.search(r'<div class="track__desc">(.+)</div>', html.text)
            name = 'test'
            if track and executor and name:
                track = track.group(1)
                executor = executor.group(1)
                button2 = types.InlineQueryResultAudio(
                    id='2', 
                    audio_url=track,
                    title=name,
                    performer=executor
                )
                bot.answer_inline_query(query.id, [button2], cache_time=1)

The problem is that the track appears in the tooltip, but when you try to send it, Failed comes out.

Answer 1

I made the same regex and the same request in the bot's PM - everything works fine.
Made from another site - the same problem, although if you insert a link that the site gives directly - everything works fine. I do through catching - does not work.
