We have a website that has an SSL Certificate from GoDaddy. Our Japanese Office is reporting that some of their clients cannot access the secure site via their mobile phone. Apparently one of the major carriers does not have root certs for GoDaddy.
Other than picking a cert from another vendor, what are our options?
Update: The reason we cannot easily change the cert vendor is the site is hosted by our software vendor, so I'm sort of at their mercy.
