Hi @mixup12,
I’ve used Google Translate to understand what you’ve written but let me see if I can help you out.
The first issue is I think is that you don’t have access to port 3000. Make sure that nodeJS is listening on the port and that you have access to it.
The second issue I believe is related to the Application. I say this because the following error
failed (111: Connection refused) while connecting to upstream, client: 176.59.97.233, server: test.trinbox.ru, request: "GET / HTTP/1.1", upstream: "http://[::1]:3000/", host: "test.trinbox.ru" 2020/12/20 17:53:13 [error] 6496#0: *17 connect() failed (111: Connection refused) while connecting to upstream, client: 176.59.97.233, server: test.trinbox.ru, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:3000/", host: "test.trinbox.ru"
Is almost every time an error somewhere with the configuration of the Application.
What you can try is, allow port 3000 and try to reach it directly to see if the App will load. Like so:176.59.97.233:3000. If this loads the IP(after you’ve allowed connecting to that port in your firewall) then you turn your attention to Nginx.
