OS Debian 10 + nginx. In my case, I unlinked the "default" page as:

  1. cd /etc/nginx/sites-enabled
  2. unlink default
  3. service nginx restart

I my case, I already have a file inside the sites-enabled.

And the issue had resolved after removing the unwanted and swap related files.

Options to try the nginx configuration is ok or not by the command

sudo nginx -t

Result:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

In my case, commenting out the wildcard directive on include in the /etc/nginx/nginx.conf worked

#include /etc/nginx/sites-enabled/*;

include /etc/nginx/sites-enabled/abcdef.com;

PS: as per the comments above, this could be a solution if there is just one configuration (either default or your custom one)

If davidjb's answer does not show multiple default_server lines, check for multiple include directives.

It is possible you accidentally included your default (or another site) twice.

In my case junk files from editor caused the problem. I had a config as below:

#...
http {
 # ...
 include ../sites/*;
}

In the ../sites directory initially I had a default.config file. However, by mistake I saved duplicate files as default.config.save and default.config.save.1. Removing them resolved the issue.

Execute this at the terminal to see conflicting configurations listening to the same port:

grep -R default_server /etc/nginx

If you're on Digital Ocean this means you need to go to /etc/nginx/sites-enabled/ and then REMOVE using rm -R digitalocean and default

It fixed it for me!

You likely have other files (such as the default configuration) located in /etc/nginx/sites-enabled that needs to be removed.

This issue is caused by a repeat of the default_server parameter supplied to one or more listen directives in your files. You'll likely find this conflicting directive reads something similar to:

listen 80 default_server;

As the nginx core module documentation for listen states:

The default_server parameter, if present, will cause the server to become the default server for the specified address:port pair. If none of the directives have the default_server parameter then the first server with the address:port pair will be the default server for this pair.

This means that there must be another file or server block defined in your configuration with default_server set for port 80. nginx is encountering that first before your mysite.com file so try removing or adjusting that other configuration.

If you are struggling to find where these directives and parameters are set, try a search like so:

grep -R default_server /etc/nginx
