hello,
I'm in the same situation ...
Also, I already have a unity account and am contasmment offline Error f3000003.
ID Error ...
Finally, under the 3072 and 3071 FSD ports are released and I constantly fail at random ...
I saw with my ISP and everything is ok on their side (test on my line! ...).
(sorry for translation, I'm French ...)
thank you for your reply
