nod-red modules doesn't find the device

[doit4fun]

Hi,
I have RM4 PRO and I've tried all the description, my node-red doesn't connect to device local.
On the app android is working. I've tried also to uncheck the Lock option and still doesn't work.
1.I've also tried to not connect it to cloud ... just to connect it to WLAN by resetting it and I didn't clicked next on the app steps as described. It connects to WLAN (because I can see it in the router) but still node-red doesn't see it. "Discover" on node red doesn't work - "No Devices Found" nodeStatus and also other nodes don't work. I is like the device has the local communication blocked. ping on the device is working also
I've tried 5f36 and 2737 as types and still no comm.

I have Firmware: v62093 and sdk: 2.16.35

could someone give me any other ideas?
