You are supposed to get different IPs when you use Cloudflare. It’s a proxy that sits between your vistors and your origin site. Those are Cloudflare proxy IPs. If you share the actual problem that you are trying to solve, maybe we can help you.
We covered this in your earlier topic. You cannot use Cloudflare proxy IPs in your DNS. You need to talk to your webserver provider to find the right IPs.
In the meantime, you should delete all the records that you have using Cloudflare proxy IPs. They will never work because those IPs don’t belong there. Add new records with your real server IP and that should clear your 1000 error.
I removed the IP address [172.67.133.32] [104.21.13.213]
Get the ones in the AAAA records, too.
ok removed AAAA records also
Excellent. Now you can obtain your origin server IP from your webhosting provider and add a new record with it.
