我正在使用discord.py 制作discord 機(jī)器人。但是當(dāng)我打開機(jī)器人時，它收到錯誤discord.errors.ConnectionClosed：WebSocket連接已關(guān)閉：代碼= 4004（私人使用），原因=身份驗(yàn)證失敗。有什么辦法可以解決這個問題嗎？我已經(jīng)嘗試過生成新的代幣，或者制作新的機(jī)器人。我現(xiàn)在使用的代碼之前運(yùn)行成功。當(dāng)我在其他計算機(jī)（沒有相同的IP）上運(yùn)行此代碼時，它可以正常工作。我怎么解決這個問題？import asyncioimport discordapp = discord.Client()def get_token(): # Get tokens from key.key    global token # This part works properly    f = open("Key.key", "r")    token = str(f.readline())@app.eventasync def on_ready(): #Login Part    print("Logining to : ")    print(app.user.name)    print(app.user.id)    print("==========")    game = discord.Game("Bot is working properly!")    await app.change_presence(status=discord.Status.online, activity=game)@app.eventasync def on_message(message):    if message.author.bot:        return None    if message.content == "!hello":        await message.channel.send("hello?")get_token()app.run(token)這是我的源代碼，下面是回溯  File "d:\Code\Project\discord_bot\Koi_Bot_Discord\Main.py", line 30, in <module>    app.run(token)  File "D:\Python\lib\site-packages\discord\client.py", line 598, in run    return future.result()  File "D:\Python\lib\site-packages\discord\client.py", line 579, in runner    await self.start(*args, **kwargs)  File "D:\Python\lib\site-packages\discord\client.py", line 543, in start    await self.connect(reconnect=reconnect)  File "D:\Python\lib\site-packages\discord\client.py", line 457, in connect    await self._connect()  File "D:\Python\lib\site-packages\discord\client.py", line 421, in _connect    await self.ws.poll_event()  File "D:\Python\lib\site-packages\discord\gateway.py", line 476, in poll_event    raise ConnectionClosed(exc, shard_id=self.shard_id) from excdiscord.errors.ConnectionClosed: WebSocket connection is closed: code = 4004 (private use), reason = Authentication failed.
