远程服务器返回错误：(553) File name not allowed

如何解决远程服务器返回错误：(553) File name not allowed

我正在尝试使用此 VB 代码将数据从我的本地计算机传输到具有 FTP 的远程计算机

Dim fwr As FtpWebRequest = FtpWebRequest.Create(FTPURL)
fwr.Credentials = New NetworkCredential (FTPUserName,FTPPassword) 
fwr.KeepAlive = False 
fwr.UseBinary = True 
fwr.Timeout = 20000
fwr.Method = WebRequestMethods.Ftp.UploadFile 


Dim FileInfo As System.IO.FileInfo(LocalFilePath + LocalFileName)
Dim FileLength as Integer = FileInfo.Length 
fwr.ContentLength = FileLength 

Dim buffLength as Integer 
if FileInfo.Length < 131072 Then 
  buffLength = FileLength 
else 
  BuffLength = 131072 
end if 
Dim buff(buffLength - 1 ) As Byte 

Dim fstream As System.IO.FileStream = FileInfo.OpenRead() 

Try 
   Dim FTPStream As System.IO.Stream = fwr.GetRequestStream()
   Dim contentLen As Integer = fstream.Read( buff,buffLength ) 
  

   Do Wile contentLen <> 0 
   FTPStream.Write(buff,contentLen)
   contentLen = fstream.Read(buff,buffLength) 
   Loop 



   FTPStream.Close()
   FTPStream.dispose() 
   fstream.Close() 
   fstream.dispose() 

   Catch ex As Exception
     ErrorMessage = ex.Message 

   End Try 
   fwr = nothing 

当我尝试与 lambda 用户传输文件时，它向我显示错误远程服务器返回错误：(553) 不允许文件名。但是当我使用 root 用户时，它工作正常
