Google Home can't find mesh point

[Cmom]

I have had a google mesh router with one point for a couple years. I got a new centurylink modem and had issues resetting everything up so factory reset everything and created a new home account (deleted the other) I was able to add my google mesh router and my nest thermostat and additional temperature sensor all without problems but I have plugged and unplugged the point a few times and it can't find it to add it. It is on with the lights too. When I specifically select that I'm trying to connect a wifi point it can't find it or sometimes says it found a chromecast in the living room and I don't even own chromecast. There are no buttons on a point to reset anything so I'm not sure what to do. There is also no QR code on the point but it hasn't even asked for it since it can't "find" it anyway.  Thanks!

Here is some general advice if you're having problems with adding additional units to the network.

The general set up guidance walk you through how to add additional units:
• https://support.google.com/googlenest/answer/9548301?hl=en

If you're using an iOS or iPadOS for the setup, see the following:
• https://support.google.com/googlenest/answer/12961504?hl=en

For whatever device you use for setup (iOS, iPadOS or Android), make sure any VPN are disabled, and that Wi-Fi and Bluetooth are enabled. Also make sure to use the latest version of the Google Home app.

Some other tips that can help:
• Place the unit you're trying to add close to the primary unit during the setup process. When setup is done and unit has updated itself and rebooted, unplug its' power and move it where you want it.
• If the additional unit also has ethernet ports, try to connect its' WAN port to the primary/main/master unit's LAN port with an ethernet cable during setup.
• IPv6 has caused trouble in the past when adding additional units. Try to disable IPv6 in the Google Home app -> WiFi (icon) -> Network settings -> Advanced networking. Keep it disabled until unit is added. Enable IPv6 again if you need it.
• If the unit you're trying to add isn't brand new, make sure it's factory reset ( https://support.google.com/googlenest/answer/6246619?hl=en ) and ready for setup.
• Try the setup process from a different iOS, iPadOS or Amdroid unit. Make sure to use the same Google account inside the Google Home app.
• Make sure not to run double NAT, as it can cause strange problems and performance degradation ( https://dongknows.com/double-nat-vs-single-nat/ ). Disable the routing functionality, DHCP, firewall and Wi-Fi in any equipment in front of the first/main/master Nest Wifi unit.
• Don't mix the new Nest Wifi Pro with older Google Wifi and Nest Wifi, as it's not backwards compatible.

Be aware that Nest Wifi units are made for different countries/regions in order to comply with Wi-Fi regulations (frequencies, channels and signal strength). Mixing units made for different regions are not supported. The Google Home app should warn you if that's the case, but it doesn't always do that.
