We recently purchased a Nest Wifi and are having issues connecting to a couple sites, receiving message "This site can't be reached".
Any suggestions why the Google Nest Wifi is "blocking" certain sites? I'm at a loss how to fix this. Thanks!
First I'd check is wether you run what's known as "double NAT": two routers with firewall, NAT and DHCP between you and the internet. This can cause strange problems like this, and is thus not recommended. Best practice is to put the ISP equipment in "bridge mode". More about double NAT:
If double NAT is not the issue, I'd try to set custom DNS settings on Nest Wifi from the Google Home app, described here:
I run Cloudflare with malware protection (220.127.116.11, 18.104.22.168):
Other alternatives include:
You could also try to set/ override DNS on the devices themselves, as a troubleshooting step before editing Nest Wifi settings.
If it's not a DNS issue either, I'd try to disable IPv6 on Nest Wifi from the Google Home app, as it has caused strange problems earlier.
