Facebook debugger hang error: operation_timeouted

When I paste my link into facebook debugger it starts clearing my page after a few seconds,

the following message was displayed

Twisting error OPERATION_TIMEOUT Operation timed out after 10000 milliseconds with 56153 out of 121251 bytes received

and every time you try, the milliseconds and bytes received are different.

There are my links http://www.hkgolden.com/articles/article.aspx?id=16639&catid=19 http://www.hkgolden.com/articles/article.aspx?id=16631&catid=26

I followed the guideline from Facebook to create an og tag and I am using APSX / C # to create my page, is there any idea to fix this? many thanks
