IPv6 not recognized on Proxmox VM

Hello community.

I’m at my wit’s end. I have Gladys on a Proxmox VM on an internal network hidden behind a Freedombox on a VM in order to secure my internal network on which I have my Zigbee gateway and my Wi-Fi devices.

I installed Gladys according to @pierre-gilles’s docker-compose on a Debian 12.

This same Debian 12 does have an IPv6 (ip address) and Gladys tells me it doesn’t see this IP and therefore can’t see Matter devices.

I don’t see what I can do to resolve my problem. If anyone has a lead for investigation, I’ll take it.

Thanks in advance.
