i just move to eu but i get a lot of Rejected untracked stratum share from pool 0

what is this message? until now i've never seen anything like this in cgminer

but the strange thing is that are registered to all reject A:77 R:40  but not to the gpu reject GPU 0 R:0 GPU1 R:0 GPU2 R:0 GPU3 R:0

I need some sort of advice or is better to go back to U.S. servers?
