This doesn't appear to be a discord.py bug.

FFmpegOpusAudio.from_probe() relies on ffprobe (optionally fall-backing to ffmpeg) to detect streams, and in this case ffprobe returns no streams for the provided url, which results raising IndexError in streams[0].

ah, would you know how to fix it?

Make sure the url is directly readable by ffmpeg, provide any required headers (e.g. a User-Agent), or bypass probing entirely and use FFmpegOpusAudio(url, ...) if the codec is already known.
