I would like to receive advice for a solution.
There seems to be no problem with the nginx connection, but the error log shows the following error.
Since I am creating a test environment, I am accessing by IP address without setting a domain, but a not found error screen is displayed.（404 Not Found nginx/1.20.1）
[root@centos]# sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
