• I created a redmine, and my host can access 192.168.33.55: 3000 through a browser.

• The virtual machine can also access its own 192.168.33.55: 3000

• So I started to modify nginx to forward port 8080 to the virtual machine.

• However, after nginx is restarted, I access 8080 and receive the 502 error.

• However, if I forward 8080 to nginx, the default 80 is acceptable.
