We are getting the error "The remote name could not be resolved:

[Mark Cooper]

We have an API that we use to integrate our time keeping system with our tasks in jira.  This has been working fine for months.

We used the C# SDK to develop our API.  Yesterday it quite working.

This is the code that bombs;

_jira = Jira.CreateRestClient(ConfigurationManager.AppSettings["JiraUrl"],
ConfigurationManager.AppSettings["userName"],
ConfigurationManager.AppSettings["passWord"]);

This is the error we get: "The remote name could not be resolved: 'foundrysoftware.atlassian.net'"

What changed to cause this to stop working.  Any help would be greatly appreciated because we are stuck in the water at the moment.
