-1 response code status on Waterfall.

Hi All,

I am observing ( -1 ) status code for a request, once ( -1 ) status code gets encountered, waterfall stop collecting the data.

Is there way to avoid -1 status code for a request. Manually I don’t see the any delay’s in the request processing. This issue is particularly seen on chrome browser.
