We’ve been made aware of a bug in Chrome version 53 that affects some Symantec, GeoTrust, and Thawte SSL/TLS certificates resulting in an error display when visiting affected websites. There are no issues with the affected certificates and websites, and replacing these certificates will not help. Symantec is a strong supporter of Google Chrome and its Certificate Transparency (CT) policies. This is entirely a bug with Certificate Transparency handling that is only present in Chrome 53.
The recommended solution is to upgrade to Chrome 54 while Google is working on a patch to resolve this issue. Other browsers (i.e., Safari, Microsoft IE, Edge, Firefox, etc.) are unaffected by this bug.
