Your virtual machine XXXXX was unexpectedly terminated

How do you get more information about why a instance creation failed (AWS for SAP S/4HANA 2021 FPS01) when you receive a error such as :

“Your virtual machine XXXXX was unexpectedly terminated. Reason : Client.InternalError:Client.InternalError: Client error on launch.”

I have added more authorization as described below :

I simply don't see why it has terminated.

How do you restart terminated instance creations? I am guessing you simply create new instance given it has been in terminated status anyway?

Thanks all!!!
