I used pm2 to run a node sample program (express sample program). It can currently be opened with http://127.0.0.1:3000. Now I want to open it with my own custom domain name, but I use nginx configuration After that, it still cannot be opened with a custom domain name (http://mydomain.com). It is ok to use 127.0.0.1 or localhost. Do I need to configure the host on this machine? However, after searching around the Internet for nginx configuration experience or instructions, none of them said that I still need to change the host. I hope someone can answer it.

Attach the configuration information of nginx.conf
