这是一个电子邮件服务器，其他人似乎都在使用相同的设置运行。出于某种原因，它对我不起作用，并且之前的“502 nginx docker”或“recv failed Connection reset by peer”的答案都没有解决它。也许这与my Nginx Vhost setup有关？
该网站在serverIP：5870上正确加载，如果我将proxy_pass http://127.0.0.1:5870;更改为proxy_pass http://example.com:5870;，则它将在example.com：5870上加载。但当我访问没有端口的网站时，它会出现502错误。
如果我设置proxy_pass http://127.0.0.1:5870;并访问example.com：5870，我得到：

The connection for this site is not secure
example.com sent an invalid response.
Try running Windows Network Diagnostics.
ERR_SSL_PROTOCOL_ERROR

字符串
如果我将proxy_pass更改为http://example.com:5870;，则会加载example.com，但会出现一个包含基本文本的“破碎”页面，URL为http：//localhost：9000/subscription/form”。

nginx错误日志显示2023/11/22 17:54:00 [error] 54579#54579: *2 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: <myip>, server: example.com, request: "GET / HTTP/2.0", upstream: "http://127.0.0.1:5870/", host: "example.com"
“recv failed 104 Connection reset by peer while阅读response header from upstream”的搜索结果都说这是一个php-fpm问题。但我还没有找到任何解决方案。php-fpm：

sudo netstat -nlpt |grep 9000

我尝试了proxy_pass的许多变体：

• proxy_pass http://example.com:5870;个
• proxy_pass http://<SERVER_IP>:5870;-与上面的结果相同。
• proxy_pass http://0.0.0.0:5870;与127.0.0.1：5870相同。
• proxy_pass http://example.com/;导致“ERR_TOO_MANY_REDIRECTS”。
• proxy_pass http://listmonk_app:5870;、proxy_pass http://app:5870;和proxy_pass http://listmonk:5870;都导致nginx errors。

我找到这个nginx resolving localhost on proxy pass并运行：

curl: (56) Recv failure: Connection reset by peer

curl 0.0.0.0:5870

我在这里尝试了一些解决方案https://serverfault.com/questions/351212/nginx-redirects-to-port-8080-when-accessing-url-without-slash
proxy_set_header Host $host:$server_port;似乎没有改变任何东西。
我也试

proxy_pass http://example.com:5870/;
  proxy_redirect http://example.com:5870/ http://example.com/;

也许这个NodeJs on nginx not working without a port number in the url是答案，但我不明白。
