iOS Question ftp.list error with B4i

[Alex.Gi]

Hello,
I've a strange error with B4i.
Same code runs well on B4A and B4J.

the following error is trigged after List command.

<B4IExceptionWrapper: Error Domain=caught_exception Code=0 "Error reading from stream: Error Domain=NSPOSIXErrorDomain Code=49 "Can't assign requested address" UserInfo={_kCFStreamErrorCodeKey=49, _kCFStreamErrorDomainKey=1}" UserInfo={NSLocalizedDescription=Error reading from stream: Error Domain=NSPOSIXErrorDomain Code=49 "Can't assign requested address" UserInfo={_kCFStreamErrorCodeKey=49, _kCFStreamErrorDomainKey=1}}>

what am I doing wrong ?


here the code:

Dim FTPC As FTP
Dim r As Int

PATH = "/files/"

FTPC.Initialize("FTPC", "192.168.1.250", "21", "user", "password")
FTPC.PassiveMode = True

FTPC.SendCommand("CWD", PATH)
Wait For FTPC_CommandCompleted (Command As String, Success As Boolean, ReplyCode As Int, ReplyString As String)
  
If Success = True Then

    FTPC.List("")
    Wait For FTPC_ListCompleted (ServerPath As String, Success As Boolean, Folders() As FTPEntry, Files() As FTPEntry)
  
    If Success = True Then
            For r = 0 To Files.Length - 1
               Log(Files(r).Name)

        '<sometyhing to do...>
        '<...>
        '<...>
    Else
        Log(LastException)     
    End If
  
Else
    Log(LastException)     
End If

Does it work if you set the path? eg:

FTPC.List("/")

FTPC.List("/")

it doesn't work with FTPC.List("/")

You will need to make more tests.

Run for example this server on the PC: https://www.b4x.com/android/forum/t...d-with-socket-and-asyncstreams.74320/#content
Make sure to open all relevant ports in Windows firewall.

Are you able to connect to this server?

within local network my iOS app runs well, with your server and with FileZilla Server

Hard to say what causes it. Might be more information in the server logs.

this is the vsftpd.log on my server:

Tue Jun 11 07:05:42 2024 [pid2] CONNECT: Client "<my ip>"
Tue Jun 11 07:05:42 2024 [pid1] [<ftp user>] OK LOGIN: Client "<my ip>"

so server side it seems OK.

I'm going crazy ))))))))))))))))
