QNAP ke BackBlaze B2: Kesalahan jaringan, tidak bisa mengunggah ke layanan cloud

SKSSF · Februari 5, 2026, 6:56pm

@SteveKo Melihat log HBS, saya melihat bahwa setiap entri pembuatan job yang gagal (yang menunjukkan error 504 gateway timeout) terjadi beberapa milidetik setelah munculnya error python (kemungkinan terkait dengan error SSL). Di bawah ini adalah contoh beberapa entri yang berurutan:

Saya kesulitan memahami log server ini…sepertinya memang terkait SSL, tapi saya tidak tahu bagaimana cara mengatasinya. Ada yang lebih paham soal log ini?

SKSSF · Februari 5, 2026, 7:10pm

Saya sudah memperbaikinya! Ternyata waktu sistem QNAP saya meleset beberapa detik (<5). Memperbarui waktu di Control Panel sepertinya membuat semuanya berjalan lagi.

Terima kasih @SteveKo atas bantuannya—melihat log HBS membantu saya memahami apa yang bisa menyebabkan error SSL. Saya tidak menyangka perbedaan waktu kurang dari 5 detik bisa menyebabkan kegagalan, tapi memperbarui waktu langsung menyelesaikan masalahnya!

NA9D · Februari 5, 2026, 8:13pm

Kabar baik!

Saya sangat menyarankan agar NAS Anda terhubung ke server NTP yang mendapatkan pembaruan secara rutin. Perbedaan waktu (clock drift) dapat menjadi penyebab masalah, terutama yang berkaitan dengan aspek keamanan.

SKSSF · Februari 5, 2026, 8:44pm

Terima kasih! Memang begitu—dan diatur untuk sinkronisasi setiap 12 jam. Sejujurnya saya tidak yakin apakah ini yang benar-benar memperbaiki masalahnya—pergeserannya kurang dari 5 detik, dan tampaknya SSL dapat mentoleransi beberapa menit ketidaksinkronan.

NA9D · Februari 5, 2026, 10:15pm

Anda akan terkejut. Saya sendiri terkejut selisihnya hanya 5 detik dalam periode 24 jam!

SKSSF · Februari 6, 2026, 7:27pm

Sial–saya salah. Ini memang memungkinkan saya membuat job backup dan memulainya, tetapi ketika gagal (saya salah mengonfigurasi caps di Backblaze) dan saya mencoba memulainya kembali, saya mendapat error. Saya sudah mencoba memulai ulang beberapa kali, mencoba membuat job backup baru, dan saya sudah sering memperbarui jam saya (memastikan sudah sesuai dengan waktu PC lokal saya yang sudah disinkronkan pada saat yang sama)–tetap tidak berhasil.

Saya mulai berpikir untuk menyerah saat ini. Ada ide lain yang bisa saya coba?

NA9D · Februari 7, 2026, 5:28am

Apakah Anda sudah berbicara dengan dukungan BackBlaze?

SKSSF · Februari 7, 2026, 7:10am

Saya akan menekan mereka lagi, tapi dukungan mereka cukup tidak membantu (harus memaksa agar bisa melewati respons otomatis AI, lalu seorang staf manusia menyuruh saya mengganti NAS atau menggunakan Cyberduck).
