TTIG connects to Wi-Fi but is always flashing green

Hi all,

My TTIG connects to Wi-Fi but is always flashing green 1/4sec.
I tried what was advised in this thread but to no avail. I tried multiple times to delete the gateway, reset TTIG, config wifi, open ports on the router, power cycle etc.

Even though I claimed it, I find it odd that the EUI does not show on the overview? Please see the screenshot.

NoEUI

Gateway EUI: 58A0CBFFFE80226A

Any help would be greatly appreciated.
