I encountered this issue when connecting to an SSL protected government portal I have access to from my mobile device when the server was protected by Comodo. Turns out some mobile devices don't have the Comodo root CA installed from the factory and need to go through an update to get the Root CA installed. Was a predominant issue with Android devices but I did hear of the same thing happening with some older iOS devices and even older blackberries. There is a page on the Comodo site where you can download the Root CA's to your device but this is mainly for computers which make it easy to add root CA's whereas most mobile devices dont support adding new root CA's except through a system update from the manufacturer.
