Unable to launch EC2 instance


I’m trying to launch an EC2 instance, but I’m getting the following error message and don’t know what to make out of it.

I tried to find similar posts but couldn’t. Please could someone help me out.


I was having the same issue.

I got it working using the classic wizard to create the instance rather than the quick launch – it gave me an option to select a subnet that way. Try using the classic wizard to create it (as long as you have an existing key it shouldn’t give you too big of a problem).
