I'm successfully using the push notifications service provided by Bluemix, but a few days ago the push service became unavailable, at least for configuration purposes.
The only hint I've got is that my trial expired and had to enter my credit card, maybe that caused this problem.
Here's the exception thrown:
Exception thrown by application class 'com.ibm.mbaas.ui.BackendUtility.getJSONResponse:-1'
javax.servlet.ServletException: UIBACK108E: Got unsuccessful response from 'https://mccp.ng.bluemix.net/login/rolecheck?role=developers&space_guid=568581a0-9bbd-4fbf-9fb0-243c0d7febc3'. The response status was 502 Bad Gateway. The response body was: "502 Bad Gateway: Registered endpoint failed to handle the request. ".
