Troubleshooting Service Startup Failure

## Symptom

After the service starts, the application window or interface does not display correctly, or the service appears to fail during startup because the screen content is abnormal.

## Cause

This issue may occur when the operating system display scaling is not set to `100%`. In some environments, non-default scaling can cause the service interface to render incorrectly and may be mistaken for a startup failure.

## Solution

### 1. Open Display Settings

On the server, open the operating system display settings and check the current screen scaling value.

### 2. Verify the Scale Setting

Locate the **Scale** or **Scale and layout** option.

If the scaling value is not set to `100%`, change it to `100%`.

### 3. Apply the Change

After updating the scaling setting, sign out and sign in again, or restart the server if required by the operating system.

### 4. Start the Service Again

Restart the service and verify that the interface displays normally.

## Additional Notes

- This issue is related to display configuration rather than the service binary itself.
- If the service still fails after the scaling is set to `100%`, review the service logs for additional startup errors.
- Use the image above as a reference for the correct display scaling configuration.
