This error typically arises during the data replication process from a source system to a target system.

  Network Issues: There may be network connectivity problems between the source and target systems, preventing the SLT system from establishing a connection.
  
  
  Authorization Issues: The user credentials used for the connection may not have the necessary authorizations to access the source or target system.
  
  
  Database Issues: The source or target database may be down or experiencing issues that prevent a successful connection.
