Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36 Example URL: https://timetotrade.eu/ Steps to reproduce the problem: 1. Visit https://timetotrade.eu/ obverse the NET::ERR_CERT_AUTHORITY_INVALID error 2. Visit https://timetotrade.com/ and obverse it works fine 3. Check the SSL and see they are both serving the same certificate which has DNS Name entries for both domains. What is the expected behavior? .eu redirects the user to .com What went wrong? Updating to Chrome 57 appeared to break the .eu SSL verification Does it occur on multiple sites: N/A Is it a problem with a plugin? No Did this work before? N/A Does this work in other browsers? Yes Chrome version: 57.0.2987.98 Channel: stable OS Version: OS X 10.12.3 Flash Version: This applies to all our subdomains to; https://streamer.timetotrade.eu https://api.timetotrade.eu

This is expected, as announced at https://security.googleblog.com/2016/10/distrusting-wosign-and-startcom.html Certificates issued by WoSign, which includes their acquisition of the company known as StartCom, are in the process of being distrusted, beginning with Chrome 56, and continuing with each release. Certificates from these authorities will need to be replaced with certificates from another CA.

The certificate is not "distrusted". It's only being rejected for aliases ending in .eu The certificate pre-dates the WoSign purchase and is valid until June.

The question though is why is Chrome trusting half of the certificate and not the other half? Both domains are being signed by the same certificate, on the same web server instance. Also, our certificates were issued before October 21, 2016 - on Tuesday, 30 June 2015 - which means (according to the blog post) they should still be trusted.

From the post: Beginning with Chrome 56, certificates issued by WoSign and StartCom after October 21, 2016 00:00:00 UTC will not be trusted. Certificates issued before this date may continue to be trusted, **for a time**, if they comply with the Certificate Transparency in Chrome policy or **are issued to a limited set of domains known to be customers of WoSign and StartCom.** Due to a number of technical limitations and concerns,** Google Chrome is unable to trust all pre-existing certificates while ensuring our users are sufficiently protected from further misissuance.** As a result of these changes, customers of WoSign and StartCom may find their certificates no longer work in Chrome 56. In subsequent Chrome releases, these exceptions will be reduced and ultimately removed, culminating in the full distrust of these CAs. I highlighted the relevant bits in **. The list shrinks with each Chrome release, and the .eu domain did not meet the list (which was limited in size and could not contain all StartCom/WoSign domains or certificates). In time, the .com domain will also be removed from the list, resulting in the same behaviour. |
