1. Can you enter this sample url http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Louisville/LOJIC_PublicSafety_Louisville/MapServer/2 in your browser and get a html response?
2. What version of WAB are you using and are you using the similar versions of the widgets (i.e. WAB 1.2 and 188.8.131.52 of eSearch?
I am using WAB 1.2 and 184.108.40.206 of the Esearch. Yes I can read the service from the browser and I can get the following service to load in WAB, Layer: Schools (ID: 0) but no other service will load, makes no sense to me...
I just added Layer: Fire Department (ID: 4) to one of my apps with eSearch widget without any issue...?
It seems that I can not access any REST service for any of the widget configurations, event the standard widgets. Any ideas?
Sounds like this is something you need to raise with your IT Dept. It is strange that I can access your services and you can not.
I can access them just not through WAB except the one I mentioned before which is not mine. Not sure what the problem is:(
Like I said it seems to be an internal issue for you as I can add your server urls without issue.
