I have the same problem. Some time ago, Philips Hue and Google home just stopped to work together, says I need to configure, but when I try, it says it does not find the Philips Bridge. I just restarted the whole bridge with the restart button, had to configure every single lamp and room, same problem. What to do?
I just started to experience the same thing - I've added new device to my shelly cloud, that device did not appear in Google Home. So I've unlinked the Shelly Cloud, but when I wanted to add it back in via "Works with google", all I'm getting the "Could not reach Shelly Cloud. Please try again".
I randomly tried to add various services, for example Foscam or any other, I'm still getting just that "Could not reach ***" toast message.
Seems to be somehow related to OnePlus, because it's not working my Nord phone, but at the same time it's working fine on my girlfriend's Samsung.
Thanks for responding.
Can you try first to unlik your Philips Hue account from the Home app, reboot your network by unplugging the router from the power source, and lastly link back Hue account on the Home app.
This should be able to resove this.
Let me know how it goes.
