I have Konnected device and Smartthings Hub. They both connect to the same internet. But I cannot discover Konnected device. The triangle error appears. I look it up to WireShark to determine if your network is correctly passing SSDP traffic from SmartThings hub to wireless network. In wireshark I saw Connected SSDP packages but not Hub packages. I couldn’t find the solution. Does anyone know how to solve this issue?
By the way I checked router settings, there was no upnp.
