Discord.ext.commands.errors.CommandInvokeError: Command raised an exception: ClientException: Not connected to voice. error when connected to voice

I hate to sound stupid on this (I probably do to some) I'm truly trying my best. I have been having issues with d.py voice. I have a bot with music bot functionality, and when I try to run the command k!play (song name) It fails saying it is not connected to the voice, when it is connected on the client side, and the code side. I don't understand what's going on. Here's the code for the whole command, and the whole error log under that:

@client.command(aliases=['p'])
async def play(ctx, *, query: t.Optional[str]):
    song_there = os.path.isfile("song.mp3")
    try:
        if song_there:
            os.remove("song.mp3")

    except PermissionError:
        return


    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    if voice is None:
        voiceChannel = ctx.message.author.voice.channel
        await voiceChannel.connect()
        print("Connected to voice")
        voice = discord.utils.get(client.voice_clients, guild=ctx.guild)

    spotify_regex1 = r"https://open.spotify.com/track/(......................)"
    spotify_regex2 = r"https://open.spotify.com/track/(.......................)(si=)(................)"

    match = re.match(spotify_regex1, query)
    is_match1 = bool(match)
    match = re.match(spotify_regex2, query)
    is_match2 = bool(match)

    if is_match1 or is_match2 is True:
        print("Trying With Spotify")
        os.system(f"spotdl '{query}'")
        await ctx.send(f"`Now Playing:`  {query}")


    ydl_opts = {

        'source_address': '0.0.0.0',
    }

    try:
        with youtube_dl.YoutubeDL(ydl_opts) as ydl:
            ydl.download([query])
            query_id = os.popen(f'youtube-dl --get-id "ytsearch:{query}"').read()
            title = os.popen(f'youtube-dl --get-title "ytsearch:{query_id}"').read()
            thumbnail_embed = os.popen(f'youtube-dl --get-thumbnail "ytsearch:{query_id}"').read()
            duration_embed = os.popen(f'youtube-dl --get-duration "ytsearch:{query_id}"').read()
            embed = discord.Embed(title="Now Playing", color=0xa00000)
            embed.set_thumbnail(url=thumbnail_embed)
            embed.add_field(name=title, value=f"`0:00 / {duration_embed}`", inline=True)
            embed.set_footer(text=f"Requested by {ctx.message.author}")
            await ctx.send(embed=embed)

    except:
        return

    for file in os.listdir("./"):
        if file.endswith(".mp3"):
            os.rename(file, "song.mp3")
            print("Changed mp3 to mp3")

    for file in os.listdir("./"):
        if file.endswith(".m4a"):

        if file.endswith(".webm"):
            os.rename(file, "song.mp3")
            print("Changed webm to mp3")

    if song_there is False:
        time.sleep(5)
        await ctx.send("Song not found!")

    print("Playing File (or trying to)")

    voice.play(discord.FFmpegPCMAudio("song.mp3"))
    voice.source = discord.PCMVolumeTransformer(voice.source)
    voice.source.volume = 0.80
