I've deployed my bot on railway.com

It is a music bot and is expected to play songs in vc.

The problem is , whenever it joins vc and starts to play music , the moment it starts the music , the bot just disconnects instantly.

If you think this is a code error I'll put my repository but I've also launcher the same bot on my vs code and it works fine there , it's happening on railway.
