I follow google's tutorial to add an SSL to my custom domain.
From Google Apps, I have added my app as a service. Then, I can add an URL with the domain of my choice. But when I try, I have an error "incorrect domain".
I didn't have this error with the principal domain, but only with the second (that I have added two months before, operating for mails).
Have you an idea of where could be my error?
The answer from google support:
"Unfortunately Google Apps does not support secondary domains for your App Engine app" "The only solution would be to use your primary domain or set up a new account"
