Banner Ads failing to load with LevelPlay (Error Code 509 No Mediation Fill)

When I build my game into an .apk file and run it, no banner ads appear whatsoever. I did some debugging and found that the banner ads are not appearing due to this error (Error Code 509 No Mediation Fill); Here is the entire error as it appeared on Android logcat

2024/12/21 19:59:40.444 20814 20839 Error Unity LevelPlayAds:ErrorMessage(LevelPlayAdError)

And here is the code I wrote for initializing the sdk, loading the ads and then showing them.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using com.unity3d.mediation;

public class LevelPlayAds : MonoBehaviour
{
    private LevelPlayBannerAd bannerAd;

    private void Awake()
    {
        DontDestroyOnLoad(this.gameObject);
        Initialize();
    }

    void Initialize()
    {
        LevelPlayAdFormat[] legacyAdFormats = new[] { LevelPlayAdFormat.REWARDED, LevelPlayAdFormat.BANNER };
        LevelPlay.OnInitSuccess += SdkInitializationCompletedEvent;
        LevelPlay.OnInitFailed += SdkInitializationFailedEvent;
        LevelPlay.Init("ID", "UserId", legacyAdFormats);
    }

    private void SdkInitializationCompletedEvent(LevelPlayConfiguration config)
    {
        Debug.Log("Initialization Complete!");
        bannerAd = new LevelPlayBannerAd("ID");
        LevelPlayAdSize adSize = LevelPlayAdSize.BANNER;
        LoadBannerAd();
    }

    private void SdkInitializationFailedEvent(LevelPlayInitError config)
    {
        Debug.Log("Initialization Failed :(");
        LevelPlay.OnInitSuccess -= SdkInitializationCompletedEvent;
        LevelPlay.OnInitFailed -= SdkInitializationFailedEvent;
        Initialize();
    }

    void OnApplicationPause(bool isPaused)
    {
        IronSource.Agent.onApplicationPause(isPaused);
    }

    void LoadBannerAd()
    {
        bannerAd.LoadAd();
        Debug.Log("Loading Ad...");
        bannerAd.OnAdLoadFailed += ErrorMessage;
        bannerAd.OnAdLoaded += ShowBanner;
    }

    void ShowBanner(LevelPlayAdInfo config)
    {
        Debug.Log("The has been loaded and should be displayed!");
        bannerAd.ShowAd();
    }

    void ErrorMessage(LevelPlayAdError config)
    {
        Debug.LogError("Ad failed to load D:");
        Debug.LogError("Error Code: " + config.ErrorCode);
        Debug.LogError("Error Message: " + config.ErrorMessage);
    }
}

I looked around for solutions but so far I found nothing; I set everything up for my project in IronSource and Unity Ads, so I truly don’t know what is going wrong here. Any help or guidance would be heavily appreciated. Thank You.

I’m seeing the same error. Were you able to resolve it?

Sadly not :frowning: I ended up just switching to admob…

Hi, sorry you could not solve it. I received the same error in one project but did not receive it in another one with the same setting being able to show the banner…??

I want to ask about your experience with AdMob: Is it working properly? is it easy to implement or a mess like Levelplay?

Thankfully It’s way easier to implement and I got banner ads working on it.
