Connection refused for Helloworld and nginx config

[John100927]

I set up f-stack on dpdk as documented under the quickstart readme at https://github.com/f-stack/f-stack and tried to run the helloworld module,the following picture is my Config.ini & nginx.conf

Config.ini

nginx.conf

and this picture is the result that run helloworld


but when i want to test the port8080, i found that i can't listen it
Is there anything i need to modify?
or the testing procedure is wrong?
It would really help if someone could help me out with this. Thank you!
