  The partner profile is incorrectly configured.
  The port settings have been changed but not updated in the partner profile.
  There are multiple ports defined for the same partner, leading to confusion.
  
  
  
  Incorrect Partner Profile: The partner profile may not be set up correctly, or the wrong partner profile is being used for the communication.
