Recently purchased Honewell T9 Smart Thermostat. I connected the device successfully to my Orbi RBR50 Router network, and shows "connected to WiFi" on thermostat, but "No Internet or Cloud connection". I have successful internet connection on all other devices. The error message is "socket connection failed. WiFi router is blocking peer to peer connection. Please check your router setting to allow proximal connectivity" How can I " Unblock, or allow proximal connectivity " to allow internet access for this device? In router settings, the device is "allowed" , but I think this is only for WiFi network. Security is set to "WPA2-PSK" Thanks

Strange that Google cannot find these phrases.  (One would think that someone had run into this before.)  I did find some Troubleshooting Tips (although the T9 model is not mentioned): https://ensupport.getconnected.honeywellhome.com/s/article/Why-is-my-Honeywell-Wi-Fi-device-not-connecting-to-the-Internet?language=en_US

Notice the concern about port restrictions and firewalls:

• Make sure ports 443 and 80 are open.
• If there is a firewall, make sure the device can connect to the following IP addresses:
  • 204.141.58.80
  • 204.141.58.81
  • 204.141.57.100
  • 204.141.57.101
  • 12.149.218.73
  • 104.209.185.251

Since the Arris TM1602 is only a telephony modem (not a router), the Orbi must be in "Router Mode" to provide IP addresses to everything connected and the Arris is certainly not blocking ports.

I have quite a few "Internet of Things" (IoT) devices, and none of them require ports 80 and 443 to be open from the Internet.  After confirming that Orbi has access control and port blocking turned off, I would contact Honeywell support.
