it gives me this error everytime
Mmm, this is pretty strange, which version of Android are you running? Did you try to use your own keystore?
6.0.1 im using the keystore the app generated
Same problem. Both with automatic and manual.. Android 6.0.1 MMB29M. Ready to provide additional information
Bingo! I solved my problem by changing the type of my keystore from the JKS to BKS-V1 using KeyStore Explorer
