Jellyfin logs not showing real IP of users - tanton - 2025-05-17
Hello
I have setup jellyfin behind caddy reverse proxy for external access and it works great. However, all users are shown the docker network ip (172.17.0.1) and not the actual ip. I have put the same IP in the known proxies setting but it's still not showing actual ip. Here is the Caddyfile section of jellyfin
}
jellyfin.domain.com {
reverse_proxy 192.168.1.x:8096
}
Here is the logs from caddy

Caddy is throwing out the x-forwarded-for headers because they're coming from untrusted IPs. I wish I knew enough about Caddy to figure out what needs to be done to get the real IPs. I gathered you can add each IP you trust as a trusted proxy, but that seems absolutely bonkers -- maybe it's your public IP or domain admin servers? In essence, you need to stop Caddy from tossing this value.

You need to enter the host ip in known proxies, which would be 192.168.1.x
After you make the change, restart the server, to apply changes.

Add caddy to the same docker network as jellyfin, and add the container hostname (ex: caddy) to known proxies
https://jellyfin.org/docs/general/post-install/networking/#known-proxies
You can add by IP, but recommend to set the container a static IP

I have tried. Still didn't work.

I just tried to add jellyfin to the same caddy network, I put caddy as known proxy and also tried the caddy network ip range but still didn't work.

^ You must restart the server for after adding the caddy ip to known proxies. Also do a hard reset on your browser. My caddy file is the same as yours and I had to do the add proxy/restart server/hard reset before it worked. I added this for my proxy: 192.168.1.xxx/24
