I get the following error as shown in the image when trying to add an A Record in the DNS. I have checked that there are no conflicts with the existing records.
Does the error mean that the IP is already being proxied via Cloudflare - if this is the case, what is the workaround to add the subdomain to our account?
You’ve hidden a significant amount of useful information. Maybe you’re trying to add a hostname there’s already a CNAME for. I’m not even sure that’s actually an error. Are you able to save that record, and does it work?
Type that IP address into the upper right box at whois.com and see who owns that IP address. If it’s Cloudflare, than that’s not the right IP address to use.
