Cause: Your client does not support TLS 1.3 or required cipher suites (AES-256-GCM). Fix: Upgrade your FTP client. Carnival's new server rejects SSLv3, TLS 1.0, and TLS 1.1. You must have TLS 1.2 or 1.3.
Cause: The new server uses aggressive PORT command blocking. Your router is likely dropping the data channel.
Fix: Switch to Passive (PASV) mode. In your client, got to Settings > FTP > Transfer Mode > Passive. Also, ensure your firewall allows high-range ephemeral ports (49152–65534). carnival internet ftp server new
