AWS https certificate additional certification required

I am trying to setup a https end point for my rest service in AWS.

I need to setup a certificate for the https protocol.

I setup with the following detail:

where mytestenv-env is the environment that I created in AWS.

But this is the error message that I get when I tried to create the certificate where it says "Additional verification required to request certificate for one or more domain names in this request."

Looks like I need to do some verification, but where?

thanks.

You can't get ssl certificate for aws provided domain for your ELB. You can only get ssl certificate for your OWN domain which you bought or at least fully control.
