TTIG Thing Indoor Gateway stuck in "establishing connection to LNS"

Hi,

Today we received our first batch of TTIG’s.
I followed the steps of https://www.thethingsnetwork.org/docs/gateways/thethingsindoor/

The gateway connects to my WiFi network, leds blinks short period red/green (connecting to CUPS I think?) and then gets stuck in blinking fast green.

The gateway shows up in my wifi network as a connected client and gets an IP address.

The gateway is registed @ TTN but status stays not connected.

Any idea what would be wrong?
