I'm sorry to hear about that! Unfortunately, automated bans for disconnections due to power outages or similar issues can't usually be lifted through Discord support. To address this, you'd need to reach out directly to Riot Games' support team and explain your situation. You can submit a ticket here: https://support-valorant.riotgames.com/hc/en-us and include any relevant details about the power cut. They may be able to review your case and assist you further.
