Error code 400 in Telegram generally indicates a 'Bad Request'. This means the server couldn't understand or process your request due to invalid syntax, missing parameters, or other client-side issues. Common causes include incorrect file types, exceeding file size limits, or problems with the message content itself. Try resending the message or file, ensuring it adheres to Telegram's specifications.
