We have set up the WebPageTest private instance and so far its working great. But I have noticed that https post call to one particular host/domain is not observed in WebPageTest private instance waterfall, but I do see that call when I monitor the traffic manually by launching the browser. This happens for all three browsers IE11, Chrome and Firefox.
I checked the wamp->bin->apache->apache2.4.9->httpd.conf file as well and there are no restrictions on any of the domain.
How do i debug this? Any pointers?
