I currently am attempting to add a new custom hostname to my domain and issue an SSL certificate to it. It has been stuck at Pending(Error) for over 24 hours. When I look at the error message it states:
“message”: “caa_error: domain_name.io”
I have been unable to contact support so far as it wants to automatically scan my domain and I have over 400k custom domains to scan and it times out doing the scan.
P.S. I do have Universal SSL setup on the main domain.
