Waiting for Connection and cannot ping the controller......

Hello,

I am setting up the AppDynamics in our Tomcat 8 server, I installed the agent by following the instruction, but the page shows me 'Waiting for Connection', and I cannot ping the service by 'ping finnplay.saas.appdynamics.com'

PING paid150.saas.appdynamics.com (198.169.195.55) 56(84) bytes of data.

Please help us to check.

Thanks.

Br,
