Original GitHub issue: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/780

I need limit max connection speed for clients and i try this lines for my config:

limit_conn perip 1;
limit_rate 10240k;
limit_conn perserver 30;

When i insert it to
server {
then server can't start and shows error:

[nginx] starting...
nginx: [emerg] zero size shared memory zone "perip"
[12/18/2020] [11:51:44 AM] [SSL ] › ✖ error Error: Command failed: /usr/sbin/nginx -t

limit_rate is working fine!

But connection limit does not work!

It would be very good if there is support for

limit_rate is working fine!

Does it? I tested the following code, but it has no effect 😢

location / {
  # limit download speed
  if ($request_method = GET ) {
    add_header Strict-Transport-Security "max-age=16552000; includeSubdomains; preload;";
    #  only for files bigger than 10MB
    limit_rate_after 10000k;
    # set speed to 10 MBit/s
    limit_rate 1250k;
  }

I even tested only limit_rate 1250k; outside the location block (= server block), but still no bandwidth limitation while downloading files 🤔

PS the Strict-Transport-Security header is set, so the condition works.
