It is possible that you may still have issues after [embedding a player in a Tizen app](🔗). The following sections address common issues that can arise.

## Debugging

If you are using the Web Simulator, debug your issue in the same manner that you would debug an issue in a web browser.

If you are using the Emulator or TV, follow these steps:

  1. Right-click on the project.

  2. Select **Debug As >Tizen Web Application**. A web inspector will appear.

## Possible Issues

The following topics address possible issues you may encounter when embedding a player in a Tizen app:

<br />

If you are having issues running the app on the web simulator or emulator, you may need to use a Tizen certificate instead of a Samsung Certificate:

  1. Select **Tools > Certificate Manager**.

  2. Click the **+** next to **Certificate Profile**.

  3. Select **Tizen**.

  4. Follow the prompts.

  2. Select **Network Status > IP Settings**.

  3. Choose to **Enter Manually** DNS settings.

  4. Set **DNS Server** to _8.8.8.8_.

<details><summary><strong>App is not Loading on the TV</strong></summary>

<br />

If the app is not loading on the TV, make sure you have allowed for applications to be installed on the device:

  1. Select **Tools > Device Manager**.

  2. Right-click on the TV device.

  3. Select **Permit to Install Applications**.

<br />

</details>

<details><summary><strong>NW.js - Your Profile Cannot be Used</strong></summary>

<br />

You may see this alert when running the application on the Web Simulator.

"Your profile can not be used because it is from a newer version of NW.js" alert

<br />

To prevent this alert from appearing, use the following steps:

  1. Remove the **/Users/\<your_user_name>/Library/Application Support/tizen tv web simulator** folder.

  2. Restart the Web Simulator.

<br />

<details><summary><strong>Developer Tools Shows a Blank Screen when Debugging on TV or Emulator</strong></summary>

<br />

If your developer tools are not loading when you are debugging the application using the TV or the Emulator, you can configure the tools yourself:

  1. Open a new tab or window from the blank screen and navigate to **chrome://inspect**.

  2. Next to **Disable network targets**, click **Configure…**.

  3. Add `localhost:XXX`. Replace `XXX` with the port the blank screen is using. The device will appear in the **Remote Target** list on the **Devices** page (chrome://inspect/#devices).<br /><br />In the screenshot below, `43093` is the port to use that would replace `XXX`. For example: `localhost:43093`.

Blank screen at 127.0.0.1:43093

<br /> <br />

  1. In **chrome://inspect/#devices > Remote Target**, click the **inspect** link to start a remote debugging session.
