502坏网关在Ubuntu 20.04上的NGINX上运行ASP.NET Core 5网站

Question

不确定问题是什么：

502 Bad Gateway
nginx/1.18.0 (Ubuntu)

来自nginx日志：

2021/11/05 21:59:21 [error] 59385#59385: *1 connect() failed (111: Connection refused) while connecting to upstream, client: x.x.x.x, server: mydomain.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:5004/", host: "mdomain.com"

我的网站nginx-config:

listen [::]:80;
server_name mydomain.com www.mydomain.com;
return 301 https://$host$request_uri;
}

}

我的ASP.NET核心5站点：

public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
webBuilder.UseUrls("http://localhost:5004");
});

Answer 1

对于有同样问题的人，我在ASP.NET项目的url中使用了通配符，它很有效。

UseUrls("http://*:5004"(；
