Just posting a stacktrace without context will probably not get you much help. You need to give information on what you are trying to do (including what syste, what versions and relevant snippets from your yaml files.) if you expect any help. ---

I got this error message after deploying on a Ubuntu 22.04 which uses a new backend for iptables. I downgraded iptables to use iptables-legacy to fix the problem. ```auto update-alternatives --config iptables ``` (select 1 for iptables-legacy) Then re-establish symbolic links: ```auto ln -s /etc/alternatives/iptables /sbin/iptables 2>/dev/null ln -s /etc/alternatives/iptables-save /sbin/iptables-save 2>/dev/null ln -s /etc/alternatives/iptables-restore /sbin/iptables-restore 2>/dev/null ln -s /etc/alternatives/ip6tables /sbin/ip6tables 2>/dev/null ln -s /etc/alternatives/ip6tables-save /sbin/ip6tables-save 2>/dev/null ln -s /etc/alternatives/ip6tables-restore /sbin/ip6tables-restore 2>/dev/null ```
