Help me to fix "ERR_CONNECTION_REFUSED"

This question was answered by @gndo:

@Nayara - Not sure if the lack of the log file is the problem, but you could create an empty file:

## assuming you are logged in as root
touch /var/log/nginx/mysitename/access.log

The intervening directory may not be present if it fails. Create and change ownership and permissions for nginx to use:

mkdir -p /var/log/nginx/mysitename
## chown and then chmod commands here

Edit - forgot to mention about checking your firewall. See if you can access your site while on your server using curl or wget.
