.NET agent not sending data

[CommunityUser]

I have a .NET agent running on a Windows 2008 R2 servers and I don't get any data on the AppDynamics website. I'm using the SaaS model and it says the agent is connected but not sending data. I've hit my website so there should be data to send. I looked in the AgentLog.txt file and found the following error. Any ideas on why this is happening?

Hi Dan,

Please test the controller connection through .Net Agent Confuration wizard and check if you are able to connect to the controller. In case you are failing with that as well, seems there is some network issue there.
