Test Ads not loading

[ijm700]

I followed these instructions(https://mobfox.atlassian.net/wiki/spaces/PUMD/pages/512884791/AdMob-Android) to add MobFox as a mediation partner through AdMob mediation but my banners nor interstitials are loading. I have even set the hash id to the test ones, it is working fine on iOS but on android this is my logcat. btw im running API 19 on the device
