Hi, I've deactivated the MacOS advanced firewall with 'sudo pfctl -d' for few seconds before the automated agent activated it again, and my application worked perfectly in my local ip address. I've installed Sequoia latest week from scratch in my Macbook. And if I go to System Settings > Network > Firewall, the firewall is deactivated, that is weird. Only know that running that command in my console, my application worked for few seconds in my local ip.
