Or cookie or proxy problem in the interaction of server with your module.

[marcobaturan]

Hi Jdepoix,
Let me explain the context: I develop a web-app application in streamlit which use your module to take the transcription from YT videos.
The server is http://render.com, the web-app framework is Streamlit. And after read your documentation I try to add a proper format proxy and a cookies file extracted from Firefox. I set the parameters in the server and in the app following the instructions of both platforms.
But when I run the program and extract the transcript I get this error:
"""
YouTubeRequestFailed: Could not retrieve a transcript for the video https://www.youtube.com/watch?v=429 Client Error: Too Many Requests for url: https://www.google.com/sorry/index?continue=https://www.youtube.com/watch%3Fv%3DBtpBjc6IWfA&q=EgQs49mQGLznybwGIjDf9F_hZQV1QCVtKe974TO7JrTmnVk83aHZAsc8ocp9h6ml0d9PjB8OtJE62aGnoQMyAXJaAUM! This is most likely caused by: Request to YouTube failed: BtpBjc6IWfA If you are sure that the described cause is not responsible for this error and that a transcript should be retrievable, please create an issue at https://github.com/jdepoix/youtube-transcript-api/issues. Please add which version of youtube_transcript_api you are using and provide the information needed to replicate the error. Also make sure that there are no open issues which already describe your problem!

The snippet of code:
"""

json = YouTubeTranscriptApi.get_transcript(id_video, languages=['es', 'en', 'fr', 'de', 'it', 'hr', 'pt']
, proxies={

    time.sleep(3)  # avoid overload google service

"""
As you can see, I put a proxy, a cookies file and inclusive a pause of 3 seconds. I get the proxy URL froma free list of webshare.io.
In local run perfect, in the deploy server of onrender then fails. It's look like the Google Service detect eh automatic process from a server.
Thank your time and effort.
