We tested and verified this was related to the TG862’s Firewall settings. The Deco uses port

50443 and 60443 to register itself to the TP-Link Cloud, while these two ports are blocked by the

TG862’s firewall.

Solution:

1, temporarily adjust TG862’s firewall level to “Minimum Security”.

How to: Login the TG862’s web management interface, select Gateway->Firewall->IPv4.
