远程服务器上的存储文件方法的 FTPSClient 错误

如何解决远程服务器上的存储文件方法的 FTPSClient 错误

我正在尝试使用 FTPSClient 将 csv 保存到远程服务器。 我在做什么：

object SandBox extends App {


  val client = new FTPSClient("TLS",false)
  var fis: InputStream = null

  try {
    client.setConnectTimeout(6000)
    client.connect(HOST,PORT)
    client.enterLocalPassiveMode
    client.login(USER,PWD)

    var reply = client.getReplyString
    
    client.execPBSZ(0)
    client.execPROT("P")
    client.setDataTimeout(60000)
    client.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)))
    
    reply = client.getReplyString
  
    client.setFileType(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE)

    reply = client.getReplyString

    client.setBufferSize(1024)
    
    reply = client.getReplyString

    fis = new FileInputStream(new File(PATH/File.csv))

    val bool = client.storeFile("file.csv",fis)

    if(!bool){
      import java.io.IOException
      throw new IOException("Failed to store file  due to: " + client.getReplyString)
    }

    client.logout()
  } catch {
    case e: Exception =>
      e.printstacktrace()
  } finally {
    try {
      if (fis != null) {
        fis.close()
      }
      client.disconnect()
    } catch {
      case e: Exception =>
        e.printstacktrace()
    }
  }

}

尝试存储文件时发生错误；这是日志：

FTP连接成功；我也可以制作目录。 我的目录权限为 755，文件权限为 644。

我也通过 Filezilla 做了一些测试，我可以创建文件、删除文件、创建目录...

你能帮我吗？
