IPv6 address is not announced to clients

Plex Media Server Remote Access

Server Version#: 1.42.2.10156

I’m pretty sure my part of the setup is correct as far as i can see.

So i’m using (rootfull) Podman 5.6 (with --userns auto) on Fedora Linux.

Issue: My IPv6 address is not announced to clients.

How do i check? I check connections published in: https://plex.tv/api/v2/resources?X-Plex-Client-Identifier=clientidentifier&X-Plex-Token=myplextoken&includeHttps=1

It shows 2 connections: my local IPv4 (192.168.91.4) and my public IPv4.

There is no reason that plex should not pickup my IPv6. The setup is working, to confirm i have set the following:

🦸 bash-5.2# nsenter -t $(podman inspect --format '{{.State.Pid}}' systemd-plex) -n ip addr show dev eth0

    inet6 <MY PUBLIC IPv6>/64 scope global dynamic mngtmpaddr proto kernel_ra 
       valid_lft 7100sec preferred_lft 3500sec
    inet6 fe80::60cf:8400:1ea:331/64 scope link proto kernel_ll 
       valid_lft forever preferred_lft forever

Running nmap from a client on my network shows:

nmap -p 32400 <MY PUBLIC IPv6> -6
[...]
PORT      STATE SERVICE
32400/tcp open  plex

Any help or insight appreciated. As this is kinda THE use-case for IPv6 (direct device-to-device connectivity) i would love to get it to work.

As my IPv6 prefix changes every 24h (enforced by my ISP) - i would prefer to plex automatically pick it up instead of some hacky solution that updates the custom server addresses in plex everytime. I also would like to spare me a reverse proxy and a custom domain (had this before, but i want my setup to keep as simple as possible - also i didn’t see clients picking up on the IPv6 there as well).

Thank you for your help.

You need to add “includeIPv6=1” to your parameter list in your URL:
https://plex.tv/api/resources?includeIPv6=1&includeHttps=1&X-Plex-Token=

Otherwise no IPv6 addresses will be shown at the resources endpoint.

However, there are very few (if any) current Plex clients which support connections via IPv6. Apple devices used to, but that functionality has not been added back to the new experience apps yet. The possible exception to this is the Apple TV; the legacy app is still available there.

I’m pretty sure there’s a feature suggestion floating around requesting full IPv6 support across the platform; head to the Feature Suggestions area of the forums and search for “IPv6” and it should turn up as a result.

Thanks. I didn’t know it needed that extra query parameter. :slight_smile: I can indeed see my IPv6 addresses now. so i marked this as solved.

Thank you very much!
