Steps to Reproduce

1. Log in as user.
2. Click "New" button to launch new case list and work flow (View that some work types are missing).
3. Try to search for a case ID. SSLHandshake / decrypt error exceptions are received.
4. Invoke a SOAP call, notice the fail message with SSL exception error message.

Root Cause

Servers where the SOAP service is hosted was recently moved to new hardware and there was certification problem in the new box.


There are couple of options to resolve the problem.
  • Fix the certification problem with the new box or system.​
  • Revert the changes and go back to the old system or box.
