228 Entering Long Passive Mode
Entering Long Passive Mode. An extended version of passive mode that supports longer addresses, including IPv6. Largely superseded by EPSV (229).
Cuándo verás este código
After issuing the LPSV command on servers that support long addresses. Rarely seen in practice as EPSV is preferred.
Cómo solucionarlo
No fix needed, but consider using EPSV (Extended Passive Mode) instead, which is more widely supported and simpler to parse.
