Describe the bug
I have configured NPM in the correct way when it comes to port & traffic forwarding. When I use a domain with no traffic, it works well with no issue. When I use a domain with a lot of traffic on it (700-800 clients simultaneously), I get Error 503. I am using the same domain directly without passing to the proxy, and it is working perfectly fine. When I use Proxy and I keep refreshing the website, 1/4 of times works, 3/4 of times gives error 503. I use this to hide the IP of the streaming server.

""I have checked the logs and I am getting:

183#183: *127384 connect() failed (111: Connection r
efused) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: 0.0.0.0:8080,
upstream: "xx.xx.xxx.xx:8080", bytes from/to client:0/0, bytes from/to upstre
am:0/0""

Is there any way I can increase the load that it can handle? I want to set it to have no limits on traffic handling. Is there any way to do so?

An error is reported when it reaches this point.

[mynxg]

Checked the reason: Part of it is an issue with the IP range. It's more appropriate to change it to the way of using environment variables.

[mynxg]

The bug has been reproduced. The reason is that the mapping path in Docker is too long. It can be fixed by shortening the path a bit.

It has been resolved.
