just upgraded hassio on my nuc. Not using a VM or docker or anything just hassio flashed straight to the nuc ssd.
After upgrading its stopping with
nf_conntrack: default automatic helper assignment has been turned off for security reasons and CT-based firewall rule not found. Use the iptables CT target to attach helpers instead.
I’m getting this error every few hours. Requires a restart to fix as. Logbook after reboot shows all devices still working but interface and addons (NodeRed etc) don’t work.
