Today I ran into an issue with Nginx. Nginx shuts down on me when I added a new virtual host. Upon checking the error log, I found this error:

could not build the server_names_hash, you should increase server_names_hash_bucket_size: 32

This means there was an issue with the nginx server name hashes. The fix is quite simple. In the http directive in the nginx.conf file, locate server_names_hash_bucket_size, enable it and increase the value to somehting like 128

http {
  server_names_hash_bucket_size 128;
}

When you have done this. Restart nginx sudo service nginx restart and you should be fine.

I'll love to hear from you
