Cause

        
The health check API calls for verifying the status of the dp-aiassistant service fail due to the presence of HTTP proxies.  

        
Resolution

        
Workaround:

  
Verify and then remove the HTTP proxies.

  
    
   
  1. Verify the exact HTTP and HTTPS proxy syntax with an echo.   
    
      
     
    1. For example test both lowercase and uppercase letters:
      
      
      echo $http_proxy
      
      
      echo $HTTP_PROXY
      2. 
    
    2. 
   
  2. Shutdown the PPDM core
    
    
    ppdmadmin stop
    3. 
   
  3. Remove the Proxy setting and any configured HTTP Proxies identified in Step #1
    
    
    unset PROXY_ENABLED
    
    
    unset HTTP_PROXY
    
    
    unset HTTPS_PROXY
    4. 
   
  4. Start the PPDM core
    
    
    ppdmadmin start
    5.
