I use Nginx as a proxy server. Although it can perform normal proxying, the images cannot be displayed. What is the reason for this?
The following is the code of my Nginx proxy server:

    server {
        listen   8888;
        client_body_timeout 60000;
        client_max_body_size 1024m;
        send_timeout       60000;
        client_header_buffer_size 16k;
        large_client_header_buffers 4 64k;

        proxy_headers_hash_bucket_size 1024;
        proxy_headers_hash_max_size 4096;
        proxy_read_timeout 60000;
        proxy_send_timeout 60000;



        location / {
            resolver 8.8.8.8;
            proxy_pass http://$http_host$uri$is_args$args;
        }

    }

I guess it may be related to the cache time of the image, but I don’t know the specific solution yet. I hope someone can answer it.
