Timed out uploading files using the http2 protocol?

Question

• nginx version: nginx/1.23.3
• JS upload tool: axios
• Interface uri：/fp01/upload

Uploading using HTTP, protocol http1.1, upload normal

Uploading using HTTPS, protocol http1.1, upload normal

Uploading using http2, timeout

This is my nginx configuration, and location /fp01/ is the upload file interface.

server {
  listen 80;
  listen 443 ssl http2;

  ssl_certificate /usr/local/nginx/conf/ssl/key.cer;
  ssl_certificate_key /usr/local/nginx/conf/ssl/key.key;

  ssl_session_timeout 5m;
  # 空闲连接的超时时间
  http2_idle_timeout 5s;
  # 每个 HTTP/2 连接允许的最大并发流量数量
  http2_max_concurrent_streams 100;
#  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_protocols TLSv1.2;
  ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
  ssl_prefer_server_ciphers on;
  ssl_stapling on;
  ssl_stapling_verify on;

  server_name  localhost;

  charset utf-8;
  client_max_body_size 100M;
  client_body_buffer_size 512k;

  proxy_set_header REMOTE-HOST $remote_addr;
  proxy_set_header X-Real-IP    $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-NginX-Proxy true;
  proxy_pass_request_headers on;

  gzip  on;
  #低于1kb的资源不压缩
  gzip_min_length 1k;
  #压缩级别1-9，越大压缩率越高，同时消耗cpu资源也越多，建议设置在5左右。
  gzip_comp_level 5;
  #需要压缩哪些响应类型的资源，多个空格隔开。不建议压缩图片.
  gzip_types text/plain application/javascript application/x-javascript text/javascript text/xml text/css;
  #配置禁用gzip条件，支持正则。此处表示ie6及以下不启用gzip（因为ie低版本不支持）
  gzip_disable "MSIE [1-6]\.";
  #是否添加“Vary: Accept-Encoding”响应头
  gzip_vary on;

  proxy_connect_timeout 120s;
  proxy_read_timeout 120s;
  proxy_send_timeout 120s;
  send_timeout 120s;

  # 转发时带上所有请求头
  underscores_in_headers on;

  ### 删除文件接口
  location /fp01/ {
    proxy_pass http://127.0.0.1:31600/;
    proxy_set_header Host $http_host;
  }
}

How can I make http2 faster? Alternatively, when requesting uri of/fp01/upload, use http1.1？ Please help me, thank you！

I set the timeout to 600000 and used the http2 protocol, which succeeded.

But he's not the speed I want, it's too slow!

From fiddler packet capture, it can be seen that four requests were sent simultaneously, resulting in only one TCP connection
