Service bus configuration

I will try to detail my problem, I have WCF project hosted in IIS with the auto start enabled option of the app fabric configured but even so the project only starts in the azure relay when accessing the service url ...

After a while the relay disappears.

IIS 8 Auto fabric 1.1 VS 2013

Later I'll post on azure - > web application.
