i can't visit the site except using the proxy,but still can't log in,so i want to ask if anybody know the host of tti

why can't u visit the site except with proxy?!

I don't know why actually,but chinese ip can't visit it without change the host

That doesn't sound like a host address issue. Have chinese IPs been banned?

that is unlikely...i don't think TTi bans any country?
it could be the other way around like an ISP issue or something...
