Platform/OS

Windows

OS version

Windows 10/11

Hiddify Version

2.0.5, 2.1.5, 2.5.7

What Happened?

After importing a subscription link in the Hiddify app, I encounter the error:

"Failed to add profile" - "Unexpected connection error"

The imported configuration is confirmed to be correct, as it works on other devices and platforms using the same subscription. However, this issue occurs only on some devices.

Minimal Reproducible Example (MRE)

1. Install a fresh Windows 11 system
2. Install Hiddify
3. Import a valid subscription link
4. Encounter the error

Expected Behavior

The subscription should be imported successfully, as it does on other devices.

Additional Context

This issue appears to be specific to certain devices. Other platforms and devices work fine with the same subscription.

Let me know if any logs or additional details are required.

UPD: Problem could be fixed by enabling "Debug mode" in app settings. After that subscription profile imported successfully.
