Unable to Run Crank in my local (Mac)

Hi @sebastienros

thanks for this benchmarking tool that you built. I am trying to bench mark a .Net core Webapi Project based on the documentation i have tried to set benchmarking.yml I was stuck with this issue.

**The specified endpoint url 'http://localhost:5010' for 'application' is invalid or not responsive: "An error occurred while sending the request."**

If i try to solve this issue by making a default route for GET this is passing but it gets failed in next step. It is trying to get the JobStatus and it gets 404.

```

**BenchMark.yml**
```

I tried your example of the hello sample still the same.

Crank command i used - **crank --config benchmark.yml --scenario hello --profile local**

Please let me know what i am doing wrong.
