I’ve been gradually requesting certificates for a few thousand domains, which is going very well. However, out of all of them, I’m having trouble with just one - proofs.ruthgillson.com
This domain correctly returns NOERROR for CAA queries on the sub and parent domain, and doesn’t appear to have any strange situations with inaccessible AAAA or DNSSEC issues. I’m stumped!
Why does this challenge never move forward?
