http submit button not working in acrobat pro

[greenlnd34]

I wanted submit data to website through http submit button. This button is only working PDF preview in LiveCycle Designer.

However, when I open in Acrobat X pro, it shows error "Invalid server response".

Would you tell me where is the problem? This button is working in LiveCycle Designer.

Strange!!!

Anyone has faced such problem? How can I solve it?
