Additional Context

Bot worked without issues for years, until today. I already tried a clean install, and resetting the bot token. Seems like others are having a similar issue: https://stackoverflow.com/questions/79664160/discord-py-bot-keeps-reconnected-and-disconnecting-from-voice-channels

yeah i have a music bot works flawlessly then randomly i got this problem and it seems to be that when i request it to join the call it will leave and join like 6 times then give up and ill get these exact same errors. I checked the code dosent seem to be an issue

[DA-344]

We've found the solution to this bug, I will PR a fix soon

[zigzag1001]

Thank you. In the meantime, is there a fork/branch/workaround I can use?

[DigiDuncan]

Can confirm, having this same issue on my TTS bot. Fix would be very helpful as this is an accessibility tool.

[Doxterpepper]

@DA-344 has an open PR https://github.com/Rapptz/discord.py/pull/10210

[gutbash]

YES IM NOT THE ONLY ONE THANK YOU

[Wubbity]

Really glad I'm not the only one having this problem. I run a bot called "CheersBot V2" and it seems to be having trouble on manual and automatic join (to Voice Channels).

[CalvinTheRed]

I am glad to see I am not the only one observing this issue, and even gladder to see a fix is already underway. I spent far too many hours hitting my head against the wall trying to debug my code or my discord bot permissions or even the discord guild voice channel settings. I am loking forward to seeing the fix released :)

[Sarabanga]

The error is still present, but only occurs on US Discord servers.

[Hayato20233]

The error is still present, but only occurs on US Discord servers.

Is there any server you recommend using for voice channels?

Rotteradm, India and Brazil are ok for me. Works good.

[ottergauze]

Still having this issue with discord-py 2.5.2 on Python 3.13.5, I ran some tests on each region, the only regions I found that consistently fail are Rotterdam, US East and US West, the rest function fine.

[DA-344]

The fix is not merged yet, so the issue is still up.

[msburgess3200]

As far as I can tell, all servers fail except those in Europe, e.g. Rotterdam works without issue.

[Timber23]

What version are you expecting this fix to be packaged in?

[DA-344]

This fix will be released in 2.6, but you can install the master branch to use it.

[clockwinder]

Do we have a guess as to when we'll see 2.6?

[Exoticinurs]

Oh man!! Had this issue too

[karelbondan]

My bot has this issue as well. It was running perfectly fine for almost a year until recently. Will we receive a hot fix for this in the near future?

[PanBohdan]

Same stuff :(

[Nekomimi21336]

私の環境の場合特定のVCチャンネルで発生するようになりました。同一のサーバーであってもVCチャンネルが異なれば問題なく動作します。 具体的にそうなった経緯は、なんらかのアクションをBotに行わせている最中にDiscord botをVCから切断しました(ユーザーの権限によるもの、disconnect()は利用していない)。 その後、元のVCチャンネルに再度接続できなくなりました。 DiscordBotの再起動、再接続にあたって待機時間を干渉させるなどして試しましたが接続できませんでした。 唯一試していないのであればホスト機の再起動ですがおそらく関係ないと思います。 これが意味するものとして、Discord.pyの問題もありますが、Discordサーバー側のロジックの問題が想定されます。 これはリージョンjapanで確認しました

[kipuki]

Currently having the same issue as @zigzag1001. This happens 40% of the time and varies by channel for some odd reason. It was working on a channel for the past while, but it stopped working now.

[kipuki]

I have a workaround for the issue on my end. This issue doesn't happen in Python 3.12, but it happens in 3.8.

[DA-344]

It's not related to Python versions, but to voice regions. The fix is available on the master branch.

Please update your discord.py version to the latest 2.6.3:

# be aware of any venvs
python -m pip install discord.py -U

Also, consider joining the support server for faster and easier help.

Oh Uhh Thanks

This still happens to me on 2.6.3 and the latest dev install. I'm in Vancouver. IDK how to fix this. ty. This is immediately fixed in any of the asian regions.

[kloklojul]

still bugged. Usually swaping regions helps but this time regions is affected
