The directions aren’t fully clear and I’m getting this with curl:
curl -I -L my.domain
curl: (6) Could not resolve host: my.domain
So what I did was this. After creating a custom domain with Heroku CLI, they told me to paste this URL to the DNS manager:
foo-bar-cuidaofidau89dygu8a.herokudns.com
So I went to my site on Cloudflare (which I previously configured with my namecheap provider, setting the Cloudflare nameservers). Then I added a CNAME record with my.domain as the name, and foo-bar-cuidaofidau89dygu8a.herokudns.com as the domain. I set to 2 minutes. I waited 10 minutes and ran curl again, and it still is showing no connection.
Wondering what I’m doing wrong, and if you could explain exactly how to plug in that Heroku DNS string they give you from the CLI.
