ipv6 error with nftables

[jknaus]

Hi, I have installed aigate on Fedora43.
When I start aigate e.g. with
aigate run -- aider
i get the following messages from iptables at startup:

[aigate] sandbox active

Is this due to Fedora using the nftables backend not resolving the ipv6 addresses correctly?
