Estou tentando retomar a transferência de um conjunto de arquivos grandes. Ambos os lados estão usando o Filezilla.

No lado do cliente, o log diz

Observe que o REST se tornou RE * T. Se houve algum problema de codificação estranho, por que o S na STOR ou no PASV funciona? Alguém já viu esse problema antes e sabe como corrigi-lo?

É muito provável que seja um firewall mucking com comandos FTP que não suporta. (Muitos firewalls do consumidor examinam o tráfego FTP para os comandos PORT e PASV e ajustam as regras de acordo.)

Desative temporariamente seu firewall ou use FTP seguro com TLS (SSL).
