Vedat Suat Kavgacı: I ran into the same problem, I think it is because the marketplace does not allow the t2.micro, which is allocated under the free version. I had to upgrade to the t2.medium to get rid of the error and launch the instance

However, after that, my instance will launch, and I am still not able to connect to it. I opened up the https port :7473 (and all the others listed) as instructed, but every request times out. I can’t connect using ssh either.

Any thoughts?
