nginx- duplicate default server error

Question

In my error log i get

[emerg] 10619#0: a duplicate default server for 0.0.0.0:80 in /etc/nginx/sites-enabled/mysite.com:4

on Line 4

Answer 1

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.
