This is not really about push notifications...
You have an extra leading slash in the used URL: "//apps".
[ERROR ] FWLSE0048E: Unhandled exception caught: SRVE0190E: File not
found: //apps/services/reach
Have you altered the server URL in any way?
Possible locations to look at:
The Worklight Settings screen in the device (settings.app >> your-app-name)
The Run As > Build Settings and Deploy Target window
The native\worklight.plist file
In all, try removing the trailing slash at the end. The root cause is more likely to be in the Build Settings and Deploy Target window (which will generate the URL used in the other two options).
It will also help if you will explain the way you have built your project and any related changes you may have done in it that might have triggered this.
