nginx. HTTP2. How to change keepalive_timeout?

Question

Nginx

Hello.
nginx/1.16.1
Remove keepalive_timeout from nginx.conf.
In the host config I put

server {
  listen 443 ssl http2;
  ...
  keepalive_timeout 10s;
  keepalive_requests 3;

timeout 10sec, 3 connection
requests keepalive_requests - the maximum number of requests that can be made over one keep-alive connection. After the maximum number of requests have been made, the connection is closed.

I do 5 page updates with the "Disable cache" checkbox and see how long the connection hangs on netstat -lanW .
ESTABLISHED connection hangs for 180 seconds
in the browser Connection id one for all requests.

Can you please tell me how to change the keepalive connection time correctly?
