Nest router offline

[Muts]

Just set up my mesh system yesterday. On the app the router says offline, but when I click it it says online and GREAT. The mesh point says online and seems good. 
why?

This is an issue many have been experiencing lately. Based on previous threads it seems to be related to IPv6 in Nest Wifi, but I don't know for sure what causes it. Hopefully we'll have a firmware update that fixes it soon, but no word on that from Google yet.

Least to most "destructive" things to test:

• Pull down to refresh inside the Google Home app home screen.
• Try to power cycle at least the main/ master puck.
• Try to disable then enable "Nest Wifi Cloud Services" from the Google Home app. Wi-Fi (icon) -> Settings (icon) -> Privacy settings -> Nest Wifi Cloud Services.
• Try to disable IPv6. Wi-Fi (icon) -> Settings (icon) -> Advanced networking -> IPv6.

Other relevant things to check:

• While using the Google Home app for Nest Wifi, make sure you don't have any VPN services connected. This includes "Apple iCloud Private Relay" ( https://support.apple.com/en-us/HT212614 ).
• If on iPhone, make sure the Google Home app has been granted permission for "local network support" ( https://support.google.com/chromecast/answer/7172427?hl=en ).
• Make sure you don't run double NAT: Any router in front of Nest Wifi should be in bridge mode, as Nest Wifi itself is a router with NAT, firewall and DHCP.

Hi everyone,

Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.

Thanks,
