I just installed the Engineer's Toolset for Web 11.0.2 onto my main poller. I also installed the Web-only on our web console.
If I remote desktop into each server, and launch the web console locally on each server, the toolset works fine (for testing, I'm just running a Response Time on one node). The servers both have IE 9.
If I go to our SW web console (off of the web-only server) from my desktop, and run the same test, I never get any results. It sits there saying 'Monitoring in progress', but the graph area is just white space. This happens both with Chrome 51.0.2704.106 and with IE 11.
Or is there maybe something wrong on the web server preventing external access?
