我的Web应用程序运行在http://191.101.1.48:5000我的域名itrendsolution.org有IP地址191.101.1.48 [正确指向]，但当我访问itrendsolution.org时，它显示“502 Bad gateway error nginx”。我使用cloudpanel（VPS托管）托管Flask Web应用程序，它与MySql连接。
我使用Nginx，所以当一个人访问https://itrendsolution.org时，他们会被重定向到在http [http://191.101.1.48:5000]的端口5000上运行的Web应用程序，通过Nginx配置的“代理传递”。
我有SSL证书。仍然当我访问itrendsolution.org它不工作。它显示“502坏网关错误nginx”如何使一个Web应用程序运行在http://191.101.1.48:5000得到运行在https://191.101.1.48或itrendsolution.org？
我尝试了nginx配置重定向。
nginx配置：

server {
    listen 80;
    server_name itrendsolution.org www.itrendsolution.org;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name itrendsolution.org www.itrendsolution.org;
