If you are using a specific DNS server then go to Settings > Network > Configure Internet connection > Custom and change the DNS settings. Return to the home screen and press the Options button while highlighting the application on the screen and select Check for update. If you are still having trouble then try updating your router’s firmware or try again later as it could as a result of high traffic in the server.
