Problem Description

Issue

Starting from version 2.6.2, backup uploads to S3 cloud have consistently failed without showing any error messages.
This affects both scheduled and manual backups—any upload attempt to S3 simply doesn’t go through.
A notification appears indicating the upload process has started, but the progress bar remains empty and there’s no indication of actual file transfer.
No files are uploaded, and the system provides no feedback or error messages.
Strangely, the uploaded backup temporarily shows a cloud icon, suggesting it succeeded, but the file disappears after refreshing the page.

Downloading backups from S3 is still working as expected.

Reproduction Steps

  • Schedule backup or Manual local backup
  • Upload to S3 cloud storage
  • Show uploading process notification without transfer status just blank process bar.
  • Uploaded nothing without any error massage.
