As the dashboard is getting stuck at "Loading connections" this might be because of flash security issue. Try following steps:
1. Open SWF in browser
2. Right-click on SWF -> "Global Settings"
3. "Advanced" tab

5. Add the host name of the web application server hosting the web service and "C:\"
Hope this helps.
