Need some help. Duckdns reverse proxy doesn't seem to be working.

I'm setting up a jellyfin server, and want to access it on the internet. I created a xxxxxxx.duckdns.org address for it. I have installed caddy with duckdns addon (first installed regular caddy, then overwrote /usr/bin/caddy with this custom caddy). My caddy file is as follows

XXXXXX.duckdns.org:9091 {
    reverse_proxy 127.0.0.1:8096
    tls {
        dns duckdns     XXXXXXXXXXXXXXXXX
    }
}

Started caddy and here's my status. Doesn't show any errors:

However, my reverse proxy doesn't work. I can't ping it. Same thing happens when I ping my global ip

PING xxxxxx.duckdns.org (104.183.123.226) 56(84) bytes of data.
From 192.168.1.254 (192.168.1.254) icmp_seq=4 Destination Host Unreachable
From 192.168.1.254 (192.168.1.254) icmp_seq=7 Destination Host Unreachable

I have previously setup dynamic dns successfully on raspberry pi for jellyfin, but unfortunately I didn't document the steps.

I'm on ATT Fiber with BGW320-505, and have a Deco X5700. Please advise.
