Aria 2 is found on Bluetooth, but doesn't connect

[Oliver.S.B]

My Aria 2 can be found in the Add Device section from the Fitbit App, it shows a 4 digit number. When I enter the number, it fails and shows a 'Not working?' page. Any suggestions? I've tried logging out and back in, as well as restarting my phone and the scale.

I have the same problem. My app finds the Aria 2 -> Aria 4 shows 4 numbers -> I enter them -> 0,5sec later "WLAN Problem". I tryed with 802.11b/g/n, 2,4 GHz and 35 other solutions, which dont work. it s frustrated. It s not a new Aria 2, i used them since 2019. And now it cant find my wifi.

I sent mine back, there's just too much evidence that there are fundamental
issues with the scale and the way it syncs both on Bluetooth and WiFi. I
troubleshooted the heck out of it and know when to give up! Good lucj
