since the activation of IPv6: client is not compatible with the media

[pixel24]

Hi@all,

Since my server is now connected to a pure IPv6 connection, I had to configure IPv6 in the LAN.

The setup works. The host (Ubuntu 23.04) has a valid IPv6 configuration:

Code:

root@media01:~# ip a
...
2: ens18: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 5e:xx:3a:xx:e3:xx brd ff:ff:ff:ff:ff:ff
    altname enp6s18
    inet 192.168.xx.10/24 brd 192.168.xx.255 scope global dynamic ens18
      valid_lft 42679sec preferred_lft 42679sec
    inet6 2a02:xxxx:2180:8e1c:5c20:3aff:fef7:e3ee/64 scope global dynamic mngtmpaddr
      valid_lft 86375sec preferred_lft 14375sec
    inet6 fe80::5c20:3aff:fef7:e3ee/64 scope link
      valid_lft forever preferred_lft forever

a ping6 on 2a02:xxxx:2180:8e1c:5c20:3aff:fef7:e3ee works. I then activated IPv6 in the JF backend and restarted the VM.

I can access in the browser:

https://[2a02:xxxx:2180:8e1c:5c20:3aff:fef7:e3ee]

and log in to JF. When I try to play media (music or movie) I get the message:

This client is not compatible with the media and the server is not sending a compatible media format.

I get the same message on the Android with the JF app.

Everything was fine before the changeover. What have I done wrong?
