FTP timeout issues - Solution Print

  • ftp, seedbox, file transfer, ssl, security, error 421, ftpes, ftps, filezilla, flashfxp
  • 230

Below article assumes proper connunications ports are opened to be used by respective applications such as Filezilla FTP Client, FlashFXP.

Our new seedbox servers will have SSL over FTP by default which may result in timeout on connections such as:

Response: 421 Timeout – try typing a little faster next time
Error: GnuTLS error -9: A TLS packet with unexpected length was received.
Status: Server did not properly shut down TLS connection
Error: Could not read from socket: ECONNABORTED – Connection aborted

Solution :

Kindly Choose server type : FTPES – FTP over explicit TLS/ SSL

Note: If you are using latest version of Filezilla , use

Protocol: FTP-File Transfer Protocol
Encryption: Require explicit FTP over TLS
Transfer mode: Passive

Please also make sure to allow ports for filezilla to connect.
All passive-mode FTP requires a higher level port range be made available (50000-50100).

This was tested on Filezilla FTP Client.

This is due to forced SSL connection enabled in the server end for security reasons.
