Google nest mini home is not connecting with Zyxel

Hi team,

I am using ZYXEL VMG3925-B10C model modem. I am trying to connect my Google nest mini, but I am getting an error saying password mismatch but I'm sure that the password is correct. I tried to login to the admin of my router through web. When I clicked "connection status", I can see Google home mini there without an IP address also in static state. Any help would be appreciated. Also attaching a screen shot of the same for reference. Any help would be appreciated. 

Thank you
