Hey there! This issue is likely caused by your server's firewall not having the passive FTP port range opened. You can find more details on this here:


but let me know if you need anything else!

Did you confirm the passive port range is open in the server's firewall? You wouldn't be able to test that with nmap as the ports are only used during the active FTP session, so nothing is listening on those and waiting for a connection at all times.
