I installed the Let’s Encrypt certificates on my test-server and I was expecting that the Let’s Encrypt certificates where using certificate transparancy (CT). But when I look at the transparancy indicator in Chrome, it says that the server didn’t provide CT information. I see this:
When I look for my certificate at https://crt.sh, I can find it. Also, the log operator (log.certly.io) is included in Chrome as well (see: http://www.certificate-transparency.org/known-logs). Is there something I missed? Is there additional configuration on server-side needed?
