Yesterday i had a problem with my clients being unable to connect to our Exchange server with the mobile devices and I fixed that probelm but now when my clients try to connect to the Exhcange server through the internet using RPC/HTTP in the Outlook they are unable to connect. When I run a test for functionality at this site: 
The test fails. with this message

Testing HTTP Authentication Methods for URL
       The HTTP authentication test failed.
      Additional Details
       Exception details:
Message: The underlying connection was closed: The connection was closed unexpectedly.
Type: System.Net.WebException
Stack trace:
at System.Net.HttpWebRequest.GetResponse()
at Microsoft.Exchange.Tools.ExRca.Extensions.RcaHttpRequest.GetResponse()

What do I need to do now to get this fixed?
