404:Could not find a suitable AMI

When I wanna create a new cluster following the guide, I got this error, it is too hard to debug.
Does anyone know what happened?

Hello Haoyu,

It seems to be an issue with cluster versions, we fixed it now. You can refresh your UI and try again. Let us know if you encounter any other issues
