SSL Certificate error in Chrom/IE


#1

Hello,
I used Certify (with default options) to create a new ssl certificate on my windows server 2008 R2 for my domain https://www.teamop.de
With firefox I have no problems but with IE and Chrome it shows a certificate error. In Chrome it shows ERR_CERT_AUTHORITY_INVALID. When I open the certificate details (certificate path) above my domain is “Let’s Encrypt Authority X3” with no errors and on top there is “DST Root CA X3” with an error: “This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store.” I couldn’t find out the problem.

Sounds like the machine has not had any Root Certificate Updates in a while. I don’t know how to admin Windows machines but that could be something to investigate.

Edit: are you seeing the error in IE on the machine or on another (non-Windows 2008) machine accessing the domain?

Thank you for your reply. I checked that and I got the message that this update is already installed.

I’m using my Windows 7 machine. I didn’t checked that directly on the server.

I’m not sure but it seems that my windows 7 pc has not been updated the certificates automatically since a while. On other machines the domains seems to be okay in chrome/ie. So I found this solution:


After importing the required certificate (DST Root CA X3) on to my windows 7, it works fine.
