I'm trying to add webb app to Amazon store and this is now stopping us to continue. There is notification that "The SSL certificate used by your web app is invalid" We have had no issues with our SSL before and it's from Gandi.

Thanks for posting! Dev Portal now requires secure connection for all new web apps and updates, hence this requirement. Generally, if your certificate is signed by an Amazon-approved certificate authority, it will be supported. Please review the list of Amazon approved certificates: https://wiki.mozilla.org/CA:IncludedCAs
Otherwise, you will need to use a supported certificate. As an example, certificates from DigiCert, Thawte, Entrust, and Verisign should work without any issues. Thanks!
