Solution 1:

certificate need to contain Subject Alternativ Name

I had a similar issue with our internal websites. I have certificate of my certification authority in computer root trusted store without no result. The main problem was in the little detail, my certificate doesnt contain section: Subject Alternativ Name. Google Chrome showing that error itself ["F12" ">>" "security"].

Solution 2:

Two things:

  1. You need to set the certificate as trusted within Windows's certificate store. Judging by your screen shot I'm assuming you're running Windows 8.

    Windows Server https://technet.microsoft.com/en-us/library/cc754841(v=ws.11).aspx

    Windows 8 (run certmgr.msc or certlm.msc and add the cert) Why is the local certificate store missing in Windows 8.1?

  2. You need to restart Chrome. This is from my experience.
