I am trying to configure anywhere access on my server.  The operating system is Windows Server 2012 R2 datacenter with server 2012 R2 essentials features installed.  Anywhere access worked fine on our old server which was running Windows server essentials 2012 (not R2).  I have completely turned anywhere access off on the old server and released the domain name I was using.  When trying to configure anywhere access on the new server, I picked up the same domain name I used on the previous server.  I received the errors pictured below.

 I have been able to navigate to other external web pages so clearly my server is connected to the internet.  Anywhere access is not blocked by my isp.  It worked fine on the old server.  Just to make sure I called my isp and they do not block ports 80 or 443.  I definitely only have one router on my network an UPnP is enabled. Please let me know if anybody has any ideas on what I can do.  Thanks so much in advance!
