Certificate error in Windows 10

[NeOnD]

Hi,

I see "NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED" error for most of the secure websites e.g. amazon.com in Windows 10. The browser works fine in Windows 7. I'm using v2.3.5.32.

This is a bug in Chromium 53, it should be fixed in 55.
Please check your system time, is it correct? If not please synchronize your OS time with time servers.

If it is not a time issue, please attach a screenshot. And as a temporary solution, you can check the option "Skip warning about certificate error" in "Under the hood"->"HTTPS/SSL".

I checked the system time, it's set on auto-update from Server. I also tried to check/uncheck the option you mentioned but that doesn't help. It still renders amazon.com ugly (see attached).

Also attaching amazon certificate viewed from browser.

I see it's fixed with v2.3.7.50. Thanks!

Glad to hear that.

There's an option to disable Certificate Transparency option per registry https://www.chromium.org/administrators/...ledForUrls
I've tried different keys (Policies\CentBrowser, Policies\Chromium, Policies\Google, Policies\Google\Chrome) none of which worked. I don't want to upgrade, noticed a newer version has own bugs. What is the correct key?
Thanks

@tamer
Have you tried running the browser with safemode.bat(under the same directory with chrome.exe).
Maybe some extension injected http request into the https page, causing the certificate error(mixed content).

No, it's exactly Certificate Transparency issue for all symantec issued certs. 

I believe this is correct registry path, but can't get it work.
HKEY_LOCAL_MACHINE\Software\Policies\Chromium\CertificateTransparencyEnforcementDisabledForUrls

Are you still using an old version, upgrading to 2.4.2.19 may solve this issue.
Or should we disable Certificate Transparency completely in our code base?

Sorry for my late reply. I'm just asking why a "registry key" solution to disable Certificate Transparency is not working.
Yes, I'm still using 2.2.9.39. The newer version has some css flickering animation bug that pisses me off.
