I am having an issue with Unifi Firmware 5.43.23.12533 where when I send a UDP Broadcast to control a device on the network the switch just goes out into lala land and quits passing all tagged traffic, loses its IP address, and becomes completely unresponsive unless I hold down the reset button and clear the configuration.
I reverted to 4.3.20.11298 and it seems to be fine. Anybody else see this?
