IBS-TH3-WIFI - Network firewall ports

We are having problems getting the thermometer to attach to the network. I have verified that it would be on the 2.4 network. I am pretty sure that our firewall is blocking it. I tried it outside of our firewall and it works just fine. Does anyone know which ports that the IBS-TH3 talks on so i can add an exception into the firewall? Or if anyone has any other suggestions? Thanks!

When the IBS-TH3 is connected to the INKBIRD APP, you can check the MAC address of the IBS-TH3 through the ‘…’ in the upper right corner, maybe you can add it to the white list of the firewall?
