Could not resolve host after setting up Cloud Connector
I've added Cloud Connector rule to a new vanilla Cloudflare account. I'm connecting to a bucket which is accessible over the web, my MX records are working and the nameservers are correct in the WHOIS. I've never used Cloud Connector before.
. The rule deploys without error and says it will "auto configure" but I just get:
$ curl -I https://foobar.comcurl: (6) Could not resolve host: www.foobar.com
$ curl -I https://foobar.comcurl: (6) Could not resolve host: www.foobar.com
The documentation is thin. Wouldn't I need to be adding some DNS as well, or at a pinch some bucket ACLs? I did try a www CNAME record to the bucket, but i seem unable to produce any different response.
