Rally Dashboard App Times Out

Products

• Rally SaaS

Issue/Introduction

In some situations, a dashboard app may not retrieve information.

May also be seen as "#ERROR: communication failure"

Environment

Release : SAAS

Component : AGILE CENTRAL

Cause

This can sometimes be caused due to the app SDK timing out connections after 30 seconds.  This can be confirmed by viewing the developer tools and looking for a request in red that shows (canceled) as shown below

**In some cases, the request status may show Finished with a Time value showing approximately 30 seconds

Resolution

It is possible to override the default 30 second timeout.  Here is an example how to perform that. 

Rally.onReady(function () {
	
	Ext.override(Ext.data.proxy.Server, { timeout: 60000 });
	
	Ext.define('CustomApp', {
	...
	});
}
