This alert occurs when attempting to add Windows or Linux hosts using the 'Import from CSV file' option, and the CSV file contains a mix of both valid and invalid hosts.

1. Check the **Menu Notifications** to view the individual status of each host addition.

  

2. Navigate to the location of the CSV file and locate the failureHosts.txt file. This file contains a list of hosts that were unsuccessful during the import process. Ensure that the IP addresses provided in the CSV file are correct, and then attempt to add the hosts again using an updated CSV file.
