NativeAd event listener Failed



Hello, I was listening for native ad impression and click listeners. They are working good, and they are fired as soon as the event happen. I use these listeners to track impression and clicks. But while testing and investigating further. The listeners seems to work abnormal.

Actually once the ad is displayed or clicked the events are fired and i can see a log message “Successfully hit tracking endpoint”. But at some occasion, I get a log message “Failed to hit tracking endpoint” and also the listeners are successfully fired. Now i doubt whether the impression or click is successfully tracked by MoPub, always.

I hope someone would help.


Hi @raaja090,

Thanks for reaching out! Were you offline at the time you viewed the ad? If so, that will result in the failed to hit tracking endpoint error.

If you have further questions or concerns about this, please feel free to reach out to our Support Team at with the logs from your testing and they would be glad to help you look into your specific case.
