On my server, when downloading a larger file from there through curl, sometimes the speed drops to 200 kilobytes per second. Why is that? If you download through the Chrome browser, in most cases the speed is very high

there is no server block in http... how can I change the root? if I Add server block like this:
server{
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /home/workspace/www
}
it will show error:
nginx: [emerg] a duplicate default server for 0.0.0.0:80 in /etc/nginx/sites-enabled/default:22
I hope somebody can help me to solve/understand this issue as I am totally stuck.
I am a ec2 instance running nginx. This ec2 instance is behind a load balancer.
My nginx configuration, is to reverse the traffic to an external service hosted on azure.
But for demonstration purpose lets assume this external service is example.com
all my infra is working, and my nginx configuration files is like this:
# This is the new file

With this configuration everything works just fine. But if I remove the server on port 80 and keep only the 443 and reload nginx. On the browser I get the error Bad Gateway
Is the server 80 required for nginx? I checked all the documentation and couldn't find anything.
Please can anyone enlighten me on this issue or just point me on the right path? thank you so much for any help you can provide or hint.
And please if my question is not 100% clear, don't hesitate to ask for details
I had this error today with my NGINX on Vutr, with php7:
2017/08/22 07:46:09 [error] 19191#19191: *7060 upstream timed out
(110: Connection timed out) while reading response header from

I did a hard reset of the server and now everything is working fine. But what was it, why it happened and will it happen again?

Finally, i found the issue!
I had too many processes at the same time.
the problem was in php-fpm settings.
so this error I had in php logs:
(so if u have same problem check php logs)
On the web I found this article.
After I add change my www.conf file:
pm.max_children = 40
Then I restart the php-fpm:
systemctl restart php7.0-fpm.service
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;

Deploying meteor with nginx web server :
This my nginx.config file , I am getting follwing error ""map" directive is not allowed here in /etc/nginx/sites-enabled/app:2 nginx: configuration file /etc/nginx/nginx.conf test failed" while executing "sudo nginx -t"
I am using nginx as a proxy server to serve two web apps on a single server that are running on separate ports (for local development purposes). Below is the full nginx.conf file:

server {

When accessing the subdomains from the browser I see the expected content based on the web apps that are running. However, when I access the main domain through the browser (http://mysite), it displays the content from the first proxypass (news.mysite # localhost:3001). I would have expected one of the following two scenarios:
Serve content from the default directory # /var/www/html
The typical "This site can’t be reached" error in the browser.
Why is nginx proxying the first proxypass it finds by default and how can I change it?
The first server that nginx encounters for a socket will be considered the default unless you create another one that you explicitly mark as the default.
So for your case, you would want to add an additional server block as a catch all:
server {
listen 80 default_server;
root /var/www/html;
}
