Getting an Error 400 Bad Request after signing APK. Debug version runs perfectly

Hello after I signed my apk the apolloCall.callback triggers onFailure with an error 400 as message. When testing the app from android studio on my device everything runs perfectly.

Project build.gradle:

        config {
