Fix 2: Troubleshoot the Internet
Since Cracke services are dependent on the internet, there are high chances that the issue you are facing is due to some downtime on the internet.

After 60 seconds plug it back in. Reconnect your TV with the same network.
Fix 3: Reinstall App
Ideally, you should be updating your app to the latest version, but if that’s not possible, then re-installing the latest version of app will help solve the issue.

The Last thing you can do is, Uninstall the crackle app and reinstall it again on your TV login with your credentials. Your crackle should be fixed by now.
