Intermittent response from objects when page goes live

I have built a page with a number of objects which have been programmed for a response when 'hit' using the switch select logic node. All worked flawlessly in the fast viewer; however, when I put the final JSON file etc in the actual server the response was not consistent. Sometimes it would respond when clicked and sometimes not.
I can attach the file later if needed.
Thanks for all of the great work.

Is there some console output when the server doesn't response?

I can attach the file later if needed.

That would help. Attach it please.
