I have my website hosted on substack. So if you go to my_website.com you just see a substack blog at www.my_website.com. The domain and the DNS settings are managed on Cloudflare.
I have an elixir app that I want to deploy on a subdomain: elixir_app.my_website.com. Currently this elixir app is successfully running on a fly domain like awesome-breeze-3254.fly.dev
I have set a CNAME record in my Cloudflare account that points elixir_app to awesome-breeze-3254.fly.dev
I have run “flyctl certs create elixir_app.my_website.com” to generate a certificate. When I run “flyctl certs list” it tells me that the certificate is “Awaiting Confirmation”.
What further steps do I have to take to get my app running on my subdomain?
