Denes,

Please try to set a proxy server in your chrome browser. Use Bulgarian proxy for viewing hit.bg or other Bulgarian sites having denied access for users outside Bulgaria. But for viewing other (nonbulgarian) or local sites, you must disable this proxy, because all internet traffic will be redirected trough this proxy and slowing down your browser speed :) OR if you use Windows, checking box "bypass proxy settings for local addresses" is a same.
This is a short list of proxy servers in Bulgaria.
I hope it will help!
Regards!
