P2s offline, won't connect

Just bought this printer a week ago, apart from multiple "extruder overload" issues it have printed fine.

But today bambu handy says the printer is offline or busy. I have rebooted both the app and the printer. All other wifi devices works just fine. And the device responds to ping when testing connectivity from a laptop. Ive also tried to move it over to my guest wifi to no success.
Is there any other things to try other than a factory reset?
