[BUG] Download of Bambu Cloud data fails shortly after starting #32

@viruz82

Description

@viruz82

Is there an existing issue for this?

  • I have searched the existing issues

Current Behavior

When logging into a Bambu account inside the container, Bambu Studio prompts to download cloud‑stored data (profiles, settings, etc.).
The download begins but aborts after a few seconds without completing.
No explicit error message is shown in the UI.

Expected Behavior

Bambu Studio should successfully download all cloud‑stored data (profiles, settings, etc.) without interruption.

Steps To Reproduce

  • Deploy the container using the default configuration.
  • Open Bambu Studio in the browser.
  • Log in to a Bambu account.
  • Confirm the prompt to download cloud‑stored data.
  • Observe that the download starts and then stops shortly after.
