Nabu Casa and Wifi not working

Hello, I’m using HAOSS on a Rpi4, with Nabu Casa. The Rpi is connected with my ethernet cable, coming from a CPL…
However, I add several failures of my CPL, and consequently got my HA unreachable, and disconnected from my couple devices/integration connected by internet.
I wanted to set-up also the Wifi connexion, in case the CPL are down, but do not succeed to get it working :

  • Wifi appear well connected as below.

But when I diconnect the ethernet cable, it remains unreachable. My phone connected in 4G cannot connect to HA.

Any clue on what i should do?
