Nginx 与 SSL - 刷新页面显示 404

Question

我最近为我的解析服务器安装了支持 SSL 的 Nginx。

当我输入基本 https url 时，工作正常，但当我尝试刷新页面时，出现 404 错误。

可能是 Ngix 配置错误。

这是我的 nginx.conf

events {
   worker_connections 1024;
}
http{
        server_tokens off;
        charset utf-8;

        # HTTP - redirect all requests to HTTPS
        server {
                listen 80;
                listen [::]:80;
                return 301 https://$host$request_uri;
        }

        # HTTPS - serve HTML from /usr/share/nginx/html, proxy requests to /parse/
        # through to Parse Server
        server {
                        listen 443 ssl http2;

                        server_name my-app-api.ch ;

                        root /usr/share/nginx/html;
                        index index.html index.htm;

                        # Use certificate and key provided by Let's Encrypt:

                #       }
        }
}
