Can't contact any eureka nodes - possibly a security group issue?

[NicolasLoosen]

Hi,
I'm trying to fire up your application, the most of the applications works fine and ServiceA/B & C are getting registered in the eureka Client. But i keep getting errors while the Zuul Server is starting e.g.:"

com.netflix.discovery.DiscoveryClient : Can't get a response from http://127.0.0.1:8761/eureka/apps/ zuul_1 > | Can't contact any eureka nodes - possibly a security group issue? "

The Clienttrafficgenerator also keeps running in some equal trouble.
The generator isn't registered in eureka:
"

I don't understand why it says connection refused..
I hope you can help me to solve this issue.
Kinda regards
