Do you know of a way to have a global caddy setting to only allow Cloudflare IPs, but "exempt" Jellyfin?
(I posted my caddy cloudflare section down below which only works as a global setting)
You would change it from orange cloud to gray cloud to disable the proxy in your domain DNS settings.
Specifically for the jellyfin subdomain.
That would be the correct solution IMO.
I thought that is was not against their TOS now.
I haven't heard any such thing unless you are paying for their video CDN which isn't cheap
Track the CF-Connecting-IP field instead of the IP address to get the client.
I have followed that guide which let me to a few GitHub issues.
Here is what I have put in my config:
servers {
trusted_proxies cloudflare {
interval 12h
timeout 15s
}
trusted_proxies static private_ranges
client_ip_headers Cf-Connecting-Ip X-Forwarded-For
}
}
I have also added all Cloudflare IPs in Jellyfin's known proxies:
103.21.244.0/22, 103.22.200.0/22, 103.31.4.0/22, 104.16.0.0/13, 104.24.0.0/14, 108.162.192.0/18, 131.0.72.0/22, 141.101.64.0/18, 162.158.0.0/15, 172.64.0.0/13, 173.245.48.0/20, 188.114.96.0/20, 190.93.240.0/20, 197.234.240.0/22, 198.41.128.0/17
Yet, I'm still not seeing the real IPs.

You should only need to add the IP of the last proxy before reaching Jellyfin, which would be Caddy.
Using a whitelist in this manner with cloudflare may be challenging as this list can potentially change. They do have means to query it though. https://developers.cloudflare.com/api/operations/cloudflare-i-ps-cloudflare-ip-details Additionally, have you considered ipv6 support?
if you haven't solved the problem yet, I would consider switching to Apache for your reverse proxy and using mod_remoteip.
I might have to switch, as much as I like the simplicity of Caddy, I keep running into issues like this unfortunately.
Authelia has a page on cloudflare, does this help at all? Note that I use traefik as my reverse proxy and am not using any of cloudflares advanced features.

Thanks for the suggestion. I followed that and it didn't solve the problem sadly.
