Mobile App build issue

Content

Hello all,

I have created a simple mobile app and want to publish it and generate APK QR Code..

I have followed all steps mentioned in learning library (Install a Mobile Application on an Android Device) with following keys :
Keystore Password: vbcsdoc_ks_pass
Key alias: vbcsdoc_ksalias
Key password: vbcsdoc_ksalias

This error is raised : Posting to mobile build service failed: Remote mobile build service failed to build app: error code: 400: Bad key or key password could not be found. Check that your key alias, certificate common name and key password

Could someone please help ?

thanks
