Hi, I have nginx proxy manager running in docker container and it hosts wordpress. In peak time web sometimes throw "500 Internal Server Error".

When searching through the error logs I always found this:

[alert] 2190841#2190841: 1024 worker_connections are not enough
[warn] 2190841#2190841: 1024 worker_connections are not enough, reusing connections

I've wanted to increase worker_connections, but I was unlucky as the only possible way is to add it to "/data/nginx/custom/root.conf":

events {
    worker_connections  10024;
}

That resulted into this error: "events" directive is duplicate in /data/nginx/custom/root.conf:1

So I'm out of ideas and replacing /etc/nginx/nginx.conf directly seems sketchy to me. Is there another way?

Thank you.

Unfortunately there is no other way than either to edit the file inside the container each time you update or to mount a different nginx.conf into the container.

Don't want to necro, but I came here from Google and solved the issue (cleanly).

In your Docker volume for NPM, there's now a /nginx/custom folder (documented here). I made a file at /nginx/custom/events.conf and put the following contents:

worker_connections  40960;

Hope this helps someone else! ❤️
