ASP.NET core React app 404 no No webpage was found Nginx

Question

Nginx 正在运行并且能够通过 ip 地址访问默认页面，但是使用域访问带有 React 前端的 ASP.NET Core 应用程序不起作用。 Nginx 日志中没有错误出现，ASP.NET Core 服务正在运行。

这是 mydomain.conf 文件，我假设这里有问题：

server {
    server_name mydomain.com www.mydomain.com;

    root /var/www/mydomain.com/bin/Debug/net6.0/publish/wwwroot;

    index index.html;

    location / {
        proxy_pass http://localhost:5000/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        try_files $uri /index.html;
    }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
    if ($host = www.mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    if ($host = mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80;
    listen [::]:80;

    server_name mydomain.com www.mydomain.com;
    return 404; # managed by Certbot
}

提前谢谢你。

我已经尝试了各种配置设置，检查 Nginx 日志文件是否有错误，但似乎什么也没有出现。
