  Cause:
  The error message suggests that the system is unable to find a valid connection of the specified type for the given system. This can occur due to several reasons:

  Authorization Issues: The user credentials used for the connection may not have the necessary authorizations to establish the connection.
  Network Issues: There may be network connectivity issues preventing the systems from communicating.
