请尝试用
http { # 调大客户端请求头缓冲区
# client_header_buffer_size: 默认 1k,处理常规请求
# large_client_header_buffers: 默认 4 8k,处理超出常规的头部
client_header_buffer_size 16k;
large_client_header_buffers 4 64k; # 如果是作为反向代理,也要调大代理缓冲区
proxy_buffer_size 64k;
proxy_buffers 8 64k;
proxy_busy_buffers_size 128k;
}当然如果您有使用varnish,请检查
sudo systemctl status varnish
确保内容如
