Process Instances are not showing up after configuring RHPAM 7 with LDAP

Issue

• We are able to login and run the application successfully but opening the ProcessInstance view resulted in an error message:

  "Process Instances could not be loaded, Check if the jBPM Capabilities are enabled and if the remote server is correctly set up." 
  

• Attempt to open the Process Instance View in Business Central fails and the log file shows the following error:
