We have upgraded to 22.214.171.124 from 126.96.36.199 and the shared connection doesn't display essbase servers alone. It displays R&A framework and Planning but not essbase .
Couple of diagnostics that I ran :
1. http://server:port/13080/aps/APS returns hyperion provider services
2. service are up and running (oracle http server, provider web services and everything related)
3. added provider services server on EAS too
4. I have changed the Shared connections url to http://server:port/workspace/SmartViewProviders and it doesn't display the essbase servers alone whereas the planning and R&A seem to be fine. Essbase works fine from private connections.
5.On workspace , I find the enabled products checked for provider services.
