title: Flutter, Admob, suddenly ads are not showing
body: <p>firstly my interstitialAd occurs error like this</p>
  
  <pre><code>W/flutter ( 1924): onAdFailedToLoad: 2
  I/Ads     ( 1924): Ad failed to load : 2
  I/flutter ( 1924): InterstitialAd event MobileAdEvent.failedToLoad
  I/flutter ( 1924): Interstitial failed to load
  </code></pre>
  
  <p>and the bannerAd occurs error like this</p>
  
  <pre><code>[ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: PlatformException(load_failed_ad,
  cannot reload a failed ad, id=674080682, null)
  </code></pre>
  
  <p>I published app before 2months ago and until before 2weeks ago, it has been worked totally fine</p>
  
  <p>but suddenly ads don`t show and now only testAds working fine.</p>
  
  <p>actually my admob stopped like for two days the reason was invalid traffic</p>
  
  <p>(which wasn`t supposed to understand because we didn`t click ads or watching)</p>
  
  <p>and the stopping issue is solved now but since then,</p>
  
  <p>I guess it never shows now</p>
  
  <p>could anyone help this issue please?</p>
  
  <p>and I searched it but everyone says like check the internet</p>
  
  <p>(my internet is totally fine) </p>
