Aternos does not support true automatic server start
Use the Aternos website or app to start the server manually
Keep the server page open and refresh it if needed
Use the Aternos app notifications to start it faster
Set up a third-party script only if it complies with Aternos rules
Avoid using bots, auto-clickers, or unauthorized automation
If you need always-on hosting, use a paid Minecraft host instead
