unregister fails with server returned the error code 405 android

Hi all,

On my android client, I get 'unregister fail' fpr almost 5 out of 10 tries. I am using aerogear-android-1.2.0.jar in my client side. I have setup agpush server 1.0.2 on open shift. This bug is more like https://issues.jboss.org/browse/AGPUSH-515 but I am not able fix this with any of the comments made on that bug. Also I am not on cordova too. I use android.

Below is client side error:

12-30 21:23:57.670: E/WelcomeActivity(6031): The server returned the error code 405.

After rhc tools setup, I tried doing ssh into server and ../aerogear-pus/logs and in server.log file, I could not find any error over there. Am I looking at the right place?
