Can't access HA using FQDN from WAN - CloudFlared Lets Encrypt

When connecting to my HA using an FQDN that has a certificate I get an Unable to connect to Home Assistant and retry screen, but when I use its IP address and port I can log in without any issues. I’m using the Cloudflared Integration which when I look at the tunnel on CloudFlare says “Healthy”. I’m using LetsEncrypt for my certificate. What would be causing the issue of not being able to connect?

I used these instructions to setup a few months ago–> How to configure Let's Encrypt SSL Certificates for Home Assistant completely 100% free (Updated for 2022/2023)

I have the following setup in configuration.yaml
http:
#server_port: 443
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem
ip_ban_enabled: true
login_attempts_threshold: 5
use_x_forwarded_for: true
