Woke up to this email today:
"AutoSSL would normally renew this certificate now, but 7 of the website’s secured domains just failed DCV. To provide you with more time to resolve these problems, AutoSSL will defer the renewal until Jan 9, 2022 at 12:00:00 AM UTC. After that time, AutoSSL will request a replacement certificate that excludes any domains that fail DCV. At the time of this notice, the certificate will expire in 6 days, 15 hours, 7 minutes, and 29 seconds. AutoSSL did not renew the certificate for (my domain). You must take action to keep this site secure. The “cPanel” AutoSSL provider could not renew the SSL certificate without a reduction of coverage because of the following problems" ... followed by a long laundry list.
The sender is "cpanel on (my domain)." My email server is Fastmail.
Feels scammy to me, but I'd appreciate any insight. TIA.
