We’re using a very old version of cert-manager, 0.5.2 to be exact. Today we found out that all versions less than 0.8.0 started being blocked on November 1st. This is negatively impacting our customers as we are a web hosting provider. New certificates requested as well as old certificates expiring aren’t getting renewed. We will be upgrading to the latest version of cert-manager immediately.
The reason for my post is that after reading the blog post that detailed the change I realized that we never got an email with the warning. I’ve confirmed that we provided the correct email when configuring our ACME account and was wondering why we never received the emails from Let’s Encrypt.
I can provide our account ID if that helps.
