I have two domain hosted on Google App Engine which use the same SSL certificate:
They both show the SSL certificate as working in the browsers I tested (Chrome, Safari, Firefox). However this Symantec tools claims that the "pay.moveapp.co" certificate is not installed correctly:

What is going on? It doesn't give any helpful information. It says an intermediate certificate is missing, but this is false, and it is the same certificate on both domains.
