J1 Cura extension WiFi send to printer

When I first installed Cura 5.2 + J1 extension I was able to send g-code via WiFi. The extension was somehow able to detect the printer WiFi. I’ve never explicitly set it. After upgrading to Cura 5.3 and rebooting the PC, the option disappeared. Anyone else have similar issue?

The Plugin is still installed?
Printer and Computer connected to the same lokal WiFi?

I’ve been looking at cura.log and the plugin was in a discovery loop where it keeps sending packets but not getting any response. Turns out the printer wasn’t responding to the udp packets for some reason. I power-cycled the printer and the connection was established. I think the printer has some sort of timeout mechanism on its network interface.
