Installed the Active Advisor Application for APIC-EM 1.4 Beta and though there are 7 devices in the Device Inventory nothing shows up in the new module. Re-discovering the devices won't make them appear in the module either.
Test if you can ping www.ciscoactiveadvisor.com from your APIC-EM
also, have you registered to set up an ActiveAdvisor account (on the link above). You need to log into www.ciscoactiveadvisor.com. While accessing the website you need to confirm name etc.
The beta version can take 24 hours to populate (as it is careful not to overload backend API call rates).
Also if there is old version you need to stop the old version and start the new version.
The CAA app will work after upgrading to 18.104.22.1689.
