I built a website with nodejs, but other machines on the same network could not access it. I checked on the Internet, and some people said that I needed a web server to publish it, so I took nginx to reverse proxy to my nodejs, but it was very slow. You have to wait a long time for every first visit. But direct access to the nodejs port is fast. The project is very small and should not be, so I feel that the reverse proxy is not set up correctly. Solve?
