Player timeline not working properly on iOS app (Koel Player v2.2.1 on App Store)

[TNQ22]

I installed Koel using Docker (phanan/koel:7.3.1). The player works fine on both the browser and Android app, but there's an issue on iPhone: the progress bar doesn't appear or stays at 0 when playing music. It only shows correctly when paused, and resets to 0 when resumed. The same issue occurs on the iPhone browser.

When I tested the demo at demo.koel.dev (version 6.11.1), everything worked normally. I also tried running the same version via Docker (phanan/koel:6.11.1), but the issue persisted. My iPhone is running iOS 18.4.1, and I also confirmed the same problem on an older iPhone model.

Rewritten to look more intuitive below:

Issue encountered when using Koel with Docker:

• Koel installed via Docker (phanan/koel:7.3.1 (latest))

• Player:

  • ✅ Works fine on:

    • Web browser (Windows, Android)

    • Android app

  • ❌ Fails on:

    • iPhone app

    • iPhone browser (Safari, Chrome, etc.)

---

Detailed issue on iPhone:

Scenario	Time bar behavior
While playing music (Play)	Not shown / Always at 0 sec.
When pausing (Pause)	Displays correct time.
Resuming after pause (Play)	Resets to 0 sec.

Additional checks:

• Accessed Koel demo at https://demo.koel.dev (v6.11.1): ✅ Works properly

• Installed the same version via Docker (phanan/koel:6.11.1): ❌ Same issue persists

• Devices tested:

  • iPhone running iOS 18.4.1

  • Older iPhone model
    → ❌ Both show the same problem

Here is my compose file:
