Your certificate may happen to list both these formats: “only_domain_name.com” and “lower_level_name.domain_name.com”; have a look. If this is the case, one can solve the problem by separately adding each of these as custom domain names in the developer console, as if dealing with two different domain names.
This solution is described clearer in the “Issue with a new SSL Cert (You must verify ownership of this certificate's domain(s)in order to upload it)” group thread <https://groups.google.com/forum/#!topic/google-appengine/Ii1cDfum1Go>. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
