Laporan bug: Login FTP QuFTP gagal dengan 530 Login incorrect di TS-453 Pro setelah pembaruan

Halo Dukungan QNAP,

Saya ingin melaporkan apa yang tampaknya merupakan regresi autentikasi pada versi terbaru QuFTP Service.

Masalah:
Setelah memperbarui QuFTP, semua login FTP gagal dengan pesan kesalahan “530 Login incorrect”, meskipun kredensial yang digunakan sudah benar dan tidak berubah. Konfigurasi yang persis sama berjalan tanpa masalah hingga dan termasuk QuFTP versi 1.4.3. Tidak ada perubahan apa pun di sisi klien.

Lingkungan:

  • Model NAS: TS-453 Pro (Intel Celeron J1900, x86_64)
  • Versi QTS: 5.2.9.3499
  • Versi QuFTP tempat masalah terjadi: 1.4.4
  • Versi QuFTP terakhir yang diketahui berfungsi: 1.4.3
  • Klien FTP: lftp, digunakan oleh skrip upload backup otomatis (sudah lama tidak berubah)
  • Jenis akun FTP: pengguna lokal NAS

Langkah-langkah yang sudah dicek:

  • Nama pengguna dan kata sandi sudah benar dan tidak berubah.
  • Hak akses FTP sudah diaktifkan untuk akun di QuFTP Service.
  • Server FTP sudah diaktifkan di QuFTP Service.
  • Kesalahan 530 muncul setiap kali mencoba koneksi, bukan hanya lewat lftp, jadi sepertinya bukan masalah spesifik klien.

Bisakah Anda menyelidiki mengapa autentikasi gagal pada versi QuFTP saat ini di model ini? Saya dapat memberikan log kejadian QuFTP / QuLog atau diagnostik lain yang Anda butuhkan.

Sementara itu, sebagai solusi sementara, apakah mungkin Anda menyediakan QuFTP 1.4.3 QPKG (x86_64) agar saya dapat rollback ke versi terakhir yang berfungsi sembari masalah ini diselidiki?

Terima kasih.

Salam hormat

Saya sudah menjalankan QuFTP 1.4.5 selama berbulan-bulan…

Hai @yacq,

Terima kasih banyak atas tanggapan Anda dan telah berbagi informasi tambahan.

Kami ingin menyarankan untuk memperbarui QuFTP Service ke versi 1.4.5, lalu memeriksa apakah masalah login FTP sudah teratasi.

Sebagai referensi, silakan juga lihat FAQ resmi QNAP berikut ini:
https://www.qnap.com/en/how-to/faq/con_show.php?cid=3649

Jika masalah masih berlanjut setelah memperbarui QuFTP Service, kami sarankan untuk membuat tiket dukungan melalui QNAP Service Portal, agar tim kami dapat membantu memeriksa lingkungan Anda lebih lanjut:

Terima kasih kembali atas kesabaran dan kerja samanya.

Hai,

Terima kasih atas balasannya.

Saya sudah mencoba versi 1.4.5. Saya bahkan sudah mencopot lalu memasang ulang aplikasinya, namun sayangnya masih belum berhasil.

Saya sudah memeriksa izin akun pengguna yang digunakan untuk akses FTP, dan tampaknya sudah benar.

Saya juga sudah mencoba menggunakan akun admin, tetapi saya masih menerima error 530 yang sama.

Yang membuat saya heran, tidak ada informasi sama sekali di tab “Logs”.

Hai @yacq,

Terima kasih atas masukan Anda.

Untuk membantu kami menyelidiki masalah ini lebih lanjut, kami sarankan Anda untuk membuka tiket dukungan melalui QNAP Service Portal:

Tim dukungan kami akan dapat memeriksa lingkungan NAS Anda, konfigurasi QuFTP Service, log sistem, dan pengaturan terkait secara lebih detail.

Saat membuka tiket, mohon sertakan juga informasi berikut jika memungkinkan:

  • Model NAS
  • Versi firmware QTS / QuTS hero saat ini
  • Versi QuFTP Service
  • Apakah masalah terjadi setelah pembaruan firmware atau QuFTP Service
  • Screenshot atau pesan error yang menampilkan “530 Login incorrect”
  • Perubahan terbaru pada izin pengguna, izin folder bersama, atau pengaturan FTP

Informasi ini akan membantu tim dukungan kami menganalisis kasus Anda dengan lebih efisien.

Terima kasih sekali lagi atas kesabaran dan kerja sama Anda.

Hai,

Bolehkah saya meminta paket QuFTP 1.4.3?
Hal ini akan memungkinkan lingkungan saya tetap berjalan selama masalah pada versi saat ini sedang diselesaikan.

Terima kasih.

ada kabar terbaru soal ini? Saya juga mengalami masalah yang sama. Versi 1.4.5 TIDAK berfungsi. Pengguna admin bisa, pengguna non-admin tidak bisa. Error yang sama, 530 login incorrect. Sudah buat beberapa user untuk uji coba, tes semuanya. Tetap error yang sama..

Pakai TS-453D

firmware: QTS 5.2.9.3499
