Wireguard: gateway IP could not be found, after update

[d33jay]

Hello community,
I have updated to the latest version (OPNsense 24.1.3_1-amd64). Now I can no longer access the other site via my tunnel.
LOG:
wireguard   /usr/local/opnsense/scripts/Wireguard/wg-service-control.php: ROUTING: gateway IP could not be found for 172.24.16.0/24

the network is hidden behind my Wireguard tunnel.
It worked perfectly until the update.The tunnel is set up. The tunnel network is accessible. Can anyone help me with this? I'm a bit lost as the configuration or IP of the gateway should result from the configuration.
