Upgrade to 11.3 U2 network/plugin issues.

Yesterday I installed Freenas 11.3 U2 and got major problems with network and plugins who didnt install due to DNS problems. (NAT)
Today I did a fresh install of Freenas 11.1 U7 because this was the last stable version before trying the later versions, works perfect.
I then tried to upgrade from 11.1 to 11.3 from GUI, with the same result. Plugins gone and not abel to install

If trying to install plugin with DHCP, get error that freenas dont know witch NIC i default. i have igb0 and igb1 Igb0 is connected and up, igb 1 im not using.

It doesnt make any differens if I go for static ip och dhcp ip on the server either.

Seems like Im not able to run 11.3 U2 on my syststem
