I'm using VSTS and it works. After a couple of hours, it stops working with 'Configuration Needed'
Configuration Needed
Authentication needed. Error message: TF400813%3a+Resource+not+available+for+anonymous+access.+Client+authentication+required.
When I click the Configure link after it, it reconnects.
This is not desirable if I'm expecting notifications and can't tell that it is down unless I go to the dashboard.
