Solid Blue light. Not getting ip from dhcp

I booted up my first Smartthings hub last night. I was running fine for most of the night but now it is stuck with a blue / white solid light.

Tried to reboot it / reset it but still not going on-line. From the dhcp router I can see it’s not picking up any ip’s nor is it trying to. Seems like it is stuck.

I have changed cables, moved ports etc etc.

Please advise. Pretty bad start :wink:
