When you suspect that the error could be a communications issue, you will want to start by verifying that the virtual machine is running and accessible using the Windows Azure Management Portal. If the virtual machine is running and accessible, verify the following configuration settings are set correctly.
1.	If you are using a custom domain name, verify that an A or CNAME record exists in DNS.
2.	Verify that an endpoint has been created for the virtual machine if communication is originating from an external network. 
3.	If using SSL, verify that the custom domain name being used is covered by the security certificate.
4.	Verify that there are appropriate inbound and outbound rules configured on the virtual machine’s Windows firewall for the TCP port that is being used.
5.	Verify the TCP port being used is not blocked by a client-side firewall or proxy.
