OK. That did rebuild the file but still I was lost, but I did fix it.
After the network.cfg was rebuilt and the server rebooted into GUI mode I tried CA plugin and nothing. it gave me the change ur DNS page and sure enough they were from ISP so for sure the file rebuild worked. I set them to the ones recommended and still nothing. Then I remembered in a spaceinvader video I had watched on YouTube to learn a little UNRAID I was advised to turn off IPV6 and thought hmmmm, wasn't exactly the newest video so, let's turn it back on. Boom CA plugin loads and in firefox on UNRAID GUI I can load google again. Took a little and got my plex server and all working fine so far so I think I am good to go again!
I should add, with ipv6 off and my old ISP router things were fine but I had just got a new one and... Damn thing can't even port forward properly, only opens ports but you can't remap them. Useless garbage I'll have to bridge and get a real router now.
Big thanks @itimpi
