First you need to make sure that your Apache service is actually listening on port 8080. You can test that with the following command:
netstat -plant | grep 8080
If you don’t get any output then it means that you’ve not configured Apache to listen on port 8080 properly, and you need to follow the instructions in Step 2.
This is important because Nginx would be trying to connect on port 8080 with this proxy_pass rule:
proxy_pass http://your_server_ip:8080;
