使用宝塔面板添加反向代理后，没有在网站的server字段下添加

location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://127.0.0.1:5212;

    # 如果您要使用本地存储策略，请将下一行注释符删除，并更改大小为理论最大文件尺寸
    # client_max_body_size 20000m;
}

在刚开始的时候可以正常进行访问，也能使用部分，仅在如图所示BT面板自带的反向代理设置进行设置。

同时我添加了DV测试SSL证书。
但是超过几个小时后就会变成这样：
502 Bad Gateway
nginx

当我尝试在「server字段」添加上述代码，保存更改后报错如下：

error：
nginx: [warn] could not build optimal proxy_headers_hash, you should increase either proxy_headers_hash_max_size: 512 or proxy_headers_hash_bucket_size: 64; ignoring proxy_headers_hash_bucket_size

以下是英语翻译，不用重复查看：

I am sorry that my English is not good, so I can not give native english-speaking users a better reading experience, sorry in advance.

After using the BT Linux panel to add a reverse proxy, it is not added under the server field of the web site

location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://127.0.0.1:5212;

# If you are using a local storage policy, remove the next line comment and change the size to the theoretical maximum file size
    # client_max_body_size 20000m;
}

It is initially accessible as normal, but can also be partially set up using only the reverse proxy settings that come with the BT panel as shown in the figure.

I also added the DV test SSL certificate.
But after a few hours, it's like this:
502 Bad Gateway
nginx

When I try to add the above code in the server field, save the changes and report the following error:

error：
nginx: [warn] could not build optimal proxy_headers_hash, you should increase either proxy_headers_hash_max_size: 512 or proxy_headers_hash_bucket_size: 64; ignoring proxy_headers_hash_bucket_size
