kardianos / ftps Goto Github PK

Hi, I'm trying to store a file, like this:

file, err := os.Open(path)
if err != nil {
	return err
}

buff := bufio.NewReader(file)
ctx, cancel := context.WithDeadline(context.Background(), time.Now().Add(600*time.Second))
defer cancel()

c, err := ftps.Dial(ctx, dialOptions)
if err != nil {
	return err
}
fmt.Printf("Connected to %s\n", p.Url)

	err = c.Upload(ctx,  filepath.Base(path), buff)

Problem is, for large uploads (~100MB), the upload fails almost instantly. For small files (~4MB), the upload works fine. Any ideas what could cause this? Upload works fine via FileZilla / command line ftp

It is clear that the Context Deadline (600 seconds) is not respected, upload fails in about 10 secs.

Full error: Error: upload read: failed to read code, got code 450 and message Transfer aborted. Link to file server lost: 450 Transfer aborted. Link to file server lost
