Can't claim server or access unless o same subnet

was running 0.9.x on my TS-569L and went to upgrade to 1.0x - however did not go well so have to remove and re-install, no big drama.
However i can no longer claim the server so can’t manage even when connecting back to my network with VPN or stream outside. I know all the f/w ports are ok as it was working fine before the update.
Any ideas of what i may need to do differently?

Any idea’s? i think i may just have to roll back and see if that works
