Hello,
I found a few threads on this topic in the past, and it seems to still be an issue. We have a subdomain set up with Cloudflare as our DNS provider and we use the A/AAAA setup.
We were not alerted that the cert had failed to renew at 60 days and the only way to renew the cert was to delete the old one and create it again. We didn’t have to change anything in Cloudflare for the new record, so it’s very unclear to me why this didn’t work automatically.
This is a very disappointing experience, as we certainly lost signups during the downtime. Can someone shed some light on what happened here?
