When we first started nginx, we were unable to access port localhost:80

See the title information from the error.log file in the Nginx folder

This is why we should first consider that the path contains Chinese, such as sundries, which is the reason for the error

CreateFile () “D: \ Nginxginx – 1.19.0 esouce/favicon. Ico” failed (123: The filename, Directory name, or volume label syntax is incorrect), client: 127.0.0.1, server: resouce, request: “GET /favicon.ico HTTP/1.1”, host: “localhost:8081”, referrer:”http://localhost:8081/”2020/07/07 23:20:34 [notice] 5916#15948: signal process started

Instead of using \ in your path, use/so that the server does not report 500 errors
