Error 1014: CNAME Cross-User Banned with custom domain through Cloudflare
In Project Settings > General, under Custom Domains, it says:
>Set up a CNAME record for your custom domain resolving to [project ref].supabase.co with as low a TTL as possible. If you're using Cloudflare as your DNS provider, disable the proxy option.
I'm using Cloudflare as my DNS, I did exactly this, but when I go to that subdomain I see "Error 1014: CNAME Cross-User Banned." According to Cloudflare this is due to Supabase's Cloudflare setup being incorrect and that they need to fix it -- but I haven't found any complaints about this from googling or in this discord, and I can't be the first one to have this problem? (I also found a Cloudflare support thread with someone describing the same problem with a different provider, and the support person claiming it's due to the same problem.) In any case, it would be confusing if supabase's documentation makes reference to Cloudflare explicitly but it wasn't configured correctly, so I'm not sure what's going wrong here.
