Hi!
I’m experiencing the same issue.
I migrated my domain to Cloudflare registar, migration succeeded 3 days ago. My domain is still not working.
I migrated without disabling DNSSEC with the previous registar. I had to do so because old registar support is not able to remove DNSSEC (they have no DNSSEC control in their control panel and never had. They were kind to enable DNSSEC for me via a support request more then 5 years ago, but last week I contacted their technical support with a request to remove it and they refused to help me). My assumption was that Cloudflare is a leading company promoting DNSSEC, and has control for DNSSEC in control panel, lots of articles written about DNSSEC, should be easily fixed here.
After I migrated domain I went over and enabled DNSSEC, it was hanging for more than 24 with same message as above, I created a support request #2363306.
Since then I tried disabling DNSSEC and enabling it again, tried to do this with different delays, nothing helps: neither DS old records are deleted nor new DS records were put at the .com level to replace old ones.
My domain is not working for almost a week now: all resolvers respect DNSSEC nowdays, my zone domain is now signed with Cloudflare keys, but this cannot be validated with DS records.
Since domain was just migrated I cannot even migrate elsewhere to try to fix it with other registar.
I got only single response to my support request 1 day ago, and there is silence since then. I understand that “free” plans get less priority, but I payed at least for the domain transfer, Cloudflare is now registar of my domain, what else could I do to enforce DS records change?
I also understand that I may have made situation worse checking/unchecking DNSSEC option for my domain, but when you have domain not working for a week (since I changed DNS server to Cloudflare ones before migrating), have no control over DS records for my domain, and no real support from Support, I was trying every little thing I could to make it work.
I really need help! Support request #2363306
