.Net Core 3.1 Angular Starter在Linux上不提供静态文件

我正在尝试从DigitalOcean的虚拟服务器为.NETCore3.1Angular项目提供服务

首先，我为我的子域democlient.mydomain.com设置了一个Nginx服务器块，并在/var/www/democlient.mydomain.com中创建了一个简单的html文件。 然后，我使用Letsencrypt的certbot启用了SSL。 当我转到时，我会看到html文件的内容

然后，我在我的Windows 10 PC上使用.NET Core 3.1 Angular模板创建了一个新项目

dotnet new angular -o DemoClient

它在Windows 10上本地运行。我将它克隆到我位于DigitalOcean的Ubuntu 18.04机器上，并在/var/www/democlient.mydomain.com中创建了一个指向bin/Release/netcoreapp3.1/publish文件夹的符号链接。 我已经使用

dotnet publish --configuration Release

创建了一个系统服务

当我访问时，它显示“加载…”，但不确定地挂在那里。浏览器控制台还显示styles.css和runtime-es2015.js未找到。 我的应用程序似乎可以访问，但静态文件没有正确加载/提供。我的Startup.cs中确实有这个：

app.UseStaticFiles();
if (!env.IsDevelopment())
{
     app.UseSpaStaticFiles();
}

我的服务器块：

 listen 443 ssl;
 listen [::]:443 ssl;

 include snippets/ssl-democlient.mydomain.com.conf;
 index index.html index.htm index.nginx-debian.html;

 server_name democlient.mydomain.com;
 location / {
     try_files $uri $uri/ =404;

     proxy_pass              https://localhost:5001;
     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;
 }

 ssl_certificate /etc/letsencrypt/live/democlient.mydomain.com/fullchain.pem; # managed by Certbot
 ssl_certificate_key /etc/letsencrypt/live/democlient.mydomain.com/privkey.pem; # managed by Certbot

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

如果替换为，我将从democlient.mydomain.com重定向到democlient.mydomain.com:5001

我不知道该怎么做
