Edgerouter POE and Unifi AP AC light

Hi 

Im new to Ubnt, im having trouble setting ut my access point to the Edgerouter POE, it will only flash blue and not show up on my controller.

If i plug it inn to my service provider router it starts working.

Do i have to set a static IP like 192.168.1.20/24 ?  As i have it now it says to use DHCP and it does not show any IP adress.

I have tried to run the wizard.

It was working for a short while until i had to pull the power from the router.

Thanks in advance
