Failed to parse rules for signal appVM

When I start my signal I get an error saying it cant parse rules for “turn3.voip.signal.org” I look at the firewall rules and it is whitelisted

I’ve changed zero settings in signal. This is not happening to any other appVMs. Any advice would be greatly appreciated

I’ve tried different netVMs and it’s the same problem.

Fixed it by deleting the Qube and creating a new one from the template. Would like to know why it happened if anyone has any insights
