Nest router stopped working

[benchelor]

Hi. I have 3 google nest routers linked together in a mesh network. Today the router connected to my internet provider box stopped working. I have tried to factory reset it without success. It is not detected by the google home app when I try to add it.  

When I plug it in, it lights white permanently for 5 seconds and then no light at all. I never get the white pulsing light.

Any suggestions to fix this issue?

Thank you

When the main/master/primary Nest Wifi unit must be set up from scratch you must delete the whole Nest Wifi network in the Google Home app and start from scratch. The main unit can't simply be added back again.

Heres a guide that says just that, albeit for a bit different scenarion than yours:
