Hey,
I have deployed a Phoenix app on Fly.io and my DNS settings are on Cloudflare. For this, I created A and AAAA records on my domain for the IP addresses from flyctl ips list. Those records are proxied by Cloudflare. The Phoenix app is running perfectly fine when accessed at the URL provided by Fly.io. However when accessed from my custom domain, it results in a 520 HTTP error. Do I need to change something in the Phoenix app configuration for this to work?
