Node-red-contrib-ewelink cannot login anymore 403

The solution may be to consult experts with expertise in NodeRed https://tech-stack.com/services/internet-of-things

so, to make it simple:
‘node-red-contrib-ewelink’ does not work anymore since it uses V1 of the API.

migrate your flows to using ‘node-red-contrib-ewelink-cube’ which works different (instead of the login credentials for the eWelink web app, it uses a Token generated locally in the “device” (in my case, a NSPanelPro, I guess similarly on the iHost)

So, my question: is this Token working with the LAN mode? (meaning that the connection to nodered would not be lost if the external ethernet connection is off)
Thanks
