Question:

Why does the below error message occur while trying to establish a connection between Vault and an FTP client? 

Answer:

This error message appears due to either incorrect firewall settings or localhost setup. To resolve the error, reach out to an internal IT Department to troubleshoot further. One troubleshooting step to take is confirming if the error is reproducible with other FTP clients. (e.g.: TotalCommander, WinSCP).
