Google home fail to link philips hue

[bbat888]

Hello.
For some time now I've had a problem with Google home: my philips hue lights no longer work.
This prompted me to unlink / link my Philips hue account. Unfortunately, since then I've been unable to connect it, and I keep getting the same error: "could not reach philips hue".
I've since tried everything I could find on the internet (reboot the bridge, my internet, my phone, create a new hue account, "clean up" in the hue app, uninstall google home, from another phone, ...)
Note that everything works from the Philips hue app. But I can no longer control my lights by voice.
Someone have an idea, I do not know what to do!
Thanks a lot!

My issue ended up being due to my wifi routers DHCP server spanning multiple subnets. Once restricted the range to the same /24 subnet I was able to detect and reconnect Hue to Google home.

i just recently experienced this same issue where google home said all my phillips hue devices were unreachable and i unlinked accounts and was unable to re-link phillips hue. my fix was logging into the phillips hue website > click on the profile picture in the top right > my phillips hue system > and then deleting google from the apps that it was connected to. i went back to relink it and it finally worked.

Use Alexa, that’s the way I’m going as Google is now about as much use as a chocolate fire guard. They are succeeding in losing customers

Found on another thread. Delink account then Unplug bridge from power for 10 secs, relink through google home app

I had this same problem. I realized it was because I have VPN on my phone where I was trying to to connect. Once I turned it off I was able to connect.
