no DHCPv6 after Update to 24.x - no IPv6 address on LAN

[BSAfH42]

Versions   
OPNsense 24.1.4-amd64
FreeBSD 13.2-RELEASE-p10
OpenSSL 3.0.13

I have set up a new machine (to act as a cold standby) with 23.1.x and restored the complete config from the production machine. On the production machine (still on 23.1.7) IPv6 and DHCPv6 work fine.

After that I upgraded the new machine using the "update from console" to 24.1.4

Now I don't have any IPv6 addresses on any of the local interfaces (named LAN, CONSOLE , WLAN and run0_wlan1=WLANUSB) and DHCPv6 does not start at all.

all local interfaces show: (Services --> ISC DHCPv6)

Code: [Select]

Available range No available address range for configured interface subnet size.
I followed https://forum.opnsense.org/index.php?topic=34584.0 but that did not help.







My ISP is Dt. Telekom, and I get a /57 subnet from them. The WAN Interface does get a correct IPv6 address:
