Return/Continue code if yield return does not yield result?

How do I make the code continue to next steps if the yield return for WWW class does not return a value (in case the internet is down)? Currently the code is stuck at yielding value and does not go ahead.

    void Start()
    {
    
    StartCoroutine(GetTimers());
     
    }

    IEnumerator GetTimers()
    {
        WWW data = new WWW("http://TimerWebsiteHosting.com/GetTimers.php");
        yield return data;
        dataString = data.text;

        Items = dataString.Split(';');

        Timer1 = int.Parse(Items[0]);
        Timer2 = int.Parse(Items[1]);
        
    }

First of all: The WWW is by long obsolete!

You should rather use a UnityWebRequest!

You can set a timeout using UnityWebRequest.timeout

And then add an error check. On success read out the data.downloadHandler.text

IEnumerator GetTimers()
{
    using(UnityWebRequest www = UnityWebRequest.Get("http://TimerWebsiteHosting.com/GetTimers.php"))
    {
        // wait up to one second or whatever you want to use as timeout
        www.timeout = 1;

        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError)
        {
            Debug.LogError($"Downlaod failed with {www.responseCode} - {www.error}", this);
            yield break;
        }
        
        dataString = www.downloadHandler.text;
    }

    Items = dataString.Split(';');

    Timer1 = int.Parse(Items[0]);
    Timer2 = int.Parse(Items[1]);
}
