Amazon web services 504在AWS Elastic Beanstalk上运行flask应用程序时网关超时

我试图使用AWS Elastic Beanstalk运行我的烧瓶应用程序，但我面临504网关超时问题

我已经尝试了几种我发现的方法，但没有任何效果：/

目前，我的配置是这样的：

.ebextensions/python.config

option_settings:
    "aws:elasticbeanstalk:container:python":
        WSGIPath: application:application

packages:
 yum:
    python3-devel: []
    gcc: []
    mariadb-devel: []

files:
    "/etc/httpd/conf.d/wsgi_custom.conf":
        mode: "000644"
        owner: root
        group: root
        content: WSGIApplicationGroup %{GLOBAL}

container_commands:
    01_restart_nginx:
     command: "sudo service nginx reload"

.platform/nginx/conf.d/custom.conf

keepalive_timeout 3600s;
proxy_connect_timeout 3600s;
proxy_send_timeout 3600s;
proxy_read_timeout 3600s;
fastcgi_send_timeout 3600s;
fastcgi_read_timeout 3600s;

在日志文件中，错误如下所示：

/var/log/nginx/error.log

*1从上游读取响应头时上游超时（110：连接超时）

/var/log/web.stdout.log

[CRITICAL]工作线程超时
