What's the point of auto-renewing certificates on the BTA let platform?
I used to be able to automatically renew successfully before. Recently it failed and the message says that no valid DNS records were found for the domain within the last 30 days. I searched around and people say you need to change to a DNS validation certificate in order to work fine. However, after changing to a wildcard certificate, how do I set up other machines? For example, all use *.abc.com. Do I have to modify everything on each machine's宝塔后台重新签名吗?
