A big problem with WORDPRESS

Let start at the beginning,

First I had sp33dy.net field, the field was recorded on name.com and hosing was from a friend. Over a few days a problem orimeam error [Oops! This link appears to be broken.] [DNS error – can not find server]. After a few hours work site and then show the error again. I tried to exchange the field with another https://www.e-filme.biz of my friend and lafel same problem

Should mention that if you use PROXY SERVER site works.
I think it is a problem with wordpress because if the host upload a site created by me works.
