XFileSharing Pro - DNS Error

[RockDiz]

I'm getting an unknown error:

Can't connect to domain.com:80 (Bad hostname) LWP::Protocol::http::Socket: Bad hostname 'domain.com' at /usr/lib/perl5/site_perl/5.8.8/LWP/Protocol/http.pm line 51

This won't allow neither my users and me to upload files.

I resolved this problem temporarily by rebooting my server but it came up again after a few hours. I don't want to have to keep restarting my server every few hours to resolve this issue.
Thanks in advanced!

"123.567.876.123 fileserver1.site.com
123.567.876.124 fileserver2.site.com
123.567.876.125 site.com "

so i just replace site.com with my domain and that's it?
