Como diz o título, tento me conectar ao servidor inserindo minhas credenciais, e é isso que recebo:

Até onde eu sei, eu não estou sob nenhum firewall, se eu usar uma senha diferente, isso dá um erro diferente, então minhas credenciais estão corretas, o site cujos arquivos eu estou tentando acessar está funcionando tudo está bem. E eu posso fazer login e acessar os arquivos em outra conta usando o Filezilla sem alterar as configurações.
