Certificate error for download.jetbrains.com

I am getting a similar error in Chrome 41.x on OSX 10.9.4

(was trying to download the IntelliJ 14.1 update at work)

We've signed our certificate by very fresh CA from Thawte company (SHA256). So not all browsers/OS got updates.
If you update your system (just update MacOSX with last updates) - you'll get newest CA certificate from all certifacation companies and this error disappears.

This is exactly what this post was about: the certificate that you're using is not valid on some installations.

The suggestion to upgrade my system sounds a little peculiar. May I rather recommend that you contact the CA to request a refund for that broken certificate? After all, being installed as trusted CA is exactly why people are paying a lot of money for certificates... The current state is not better than a (free) self-signed certificate.

It's not broken certificate. It's just so fresh certificate because IT industry is going to replace SHA1 to SHA256 certificates.
If you update your OS to the last minor version this certificate will be trusted. It's normal to have your OS with last security fixes and updates.

Anyway this certificate affects some of our users so we're going to replace it with signed by SHA1 CA.

We've replaced certificate on https://download.jetbrains.com to signed by SHA1 CA.
Now your browser should not warn about any incompatibilities.

Thanks.

Hello Juntongma 0860.

Could you please provide the output of the  echo | openssl s_client -servername download.jetbrains.com.cn -connect download.jetbrains.com.cn:443 2>/dev/null | openssl x509 -noout -dates -issuer -subject  command? I want to take a look at the certificate you receive.
