我在尝试加载Rewarded填隙广告(真实硬件上的测试单元广告id(时，在Admob flutter中遇到SSL握手错误：
连接到广告服务器时出错：SSL握手中止：SSL=0x72ea901888：系统调用期间出现I/O错误，连接重置
我确实理解它的意思，但我相信它在后端足够可靠，我想知道我是否做错了什么。
main.dart:
...
await MobileAds.instance.initialize();
...
page.dart:
RewardedInterstitialAd? _rewardedInterstitialAd;
int _numRewardedInterstitialLoadAttempts = 0;
int maxFailedLoadAttempts = 3;
VoidCallback? _adsCallback;
...
const ADMOB_TEST_REWARDED_INTERSTITIAL_AD_UNIT_ID = "ca-app-pub-3940256099942544/5354046379";
...
String getAdmobRewardedInterstitialUnitId() {
return kDebugMode
? ADMOB_TEST_REWARDED_INTERSTITIAL_AD_UNIT_ID
: ADMOB_REWARDED_INTERSTITIAL_AD_UNIT_ID;
}
...
AdRequest createAdRequest() => AdRequest(
keywords: <String>[
'keyword1',
...
],
contentUrl: 'http://myappdomain.app',
nonPersonalizedAds: true,
);
...
void createRewardedInterstitialAd(VoidCallback adsCallback) {
_adsCallback = adsCallback;
FirebaseCrashlytics.instance.log('RewardedInterstitialAd.load()');
RewardedInterstitialAd.load(
adUnitId: getAdmobRewardedInterstitialUnitId(),
request: createAdRequest(),
rewardedInterstitialAdLoadCallback: RewardedInterstitialAdLoadCallback(
onAdLoaded: (RewardedInterstitialAd ad) {
print('$ad loaded.');
FirebaseCrashlytics.instance.log('RewardedInterstitialAd: onLoaded()');
_rewardedInterstitialAd = ad;
_numRewardedInterstitialLoadAttempts = 0;
},
onAdFailedToLoad: (LoadAdError error) {
print('RewardedInterstitialAd failed to load: $error');
FirebaseCrashlytics.instance.log('RewardedInterstitialAd: onAdFailedToLoad');
FirebaseCrashlytics.instance.recordError(error, StackTrace.empty);
_rewardedInterstitialAd = null;
_numRewardedInterstitialLoadAttempts += 1;
if (_numRewardedInterstitialLoadAttempts < maxFailedLoadAttempts) {
createRewardedInterstitialAd(adsCallback);
}
},
));
}
AndroidManifest.xml：
...
<!-- test -->
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="ca-app-pub-3940256099942544~3347511713"/>
</application>
这是我得到的：
2022-03-02 11:35:32.974 I/float:RewardedInterstitialAd加载失败：LoadAdError(代码：0，域：com.google.android.gms.ads，消息：连接到广告服务器时出错：SSL握手中止：SSL=0x72ea901888：系统调用期间I/O错误，对等方重置连接，responseInfo:responseInfo(responseId:null，mediationAdapterClassName:，adapterResponse:[](
设备上的日期/时间正常。原因可能是什么？
PS。google_mobile_ads: ^1.1.0
PPS。我可以看到Rewarded Interstial在1.1.0中处于测试版，这可能是一个错误。
PPPS。我已经在我的谷歌账户中启用了广告跟踪，并在日志中得到了这一点：

我检查了"；https://googleads.g.doubleclick.net/mads/static/mad/sdk/native/sdk-core-v40-loader.html"由于SSL问题，我也无法从桌面连接到它。
即使在出现相同错误的示例应用程序(创建了票证(中，它也不起作用。
