  Configuration Issues: There may be a misconfiguration in the UCON settings, particularly in the white list entries that define which clients and namespaces are allowed to access certain resources.
  Client-Specific Settings: The error may also arise if the settings are not properly defined for the specific client (clientmd) mentioned in the error message.
  
  Solution:
  
  
  Check UCON Configuration:
  
  Go to the UCON configuration in your SAP system (transaction code UCON or SICF for HTTP services).
  Verify that the white list entries are correctly defined for the client, entry type, and namespace mentioned in the error message.
  Ensure that the necessary authorizations are granted for the HTTP connection.
  
  
  
  Add White List Entry:

  Make sure to save and activate the changes.
  
  
  
  Check Authorization Objects:
  
  Ensure that the user or service account making the HTTP request has the necessary authorization objects assigned to it. This may involve checking roles and profiles in transaction PFCG.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation for UCON and HTTP connectivity to ensure that all necessary configurations are in place.
  
  
  
  Testing:
