SEF vs 404 Errors

[victor belizario]

Hi guys,

I really need help.

My joomla website have one issue:

In nginx vhost file, i have:
# Enabled joomla SEF URL's inside Nginx
try_files $uri $uri/ /index.php?$args;


The SEF works, but if i enter something that does not exist, like www.example.com/asdasdad, this redirect me to main page ( www.example.com ), but i want to show the joomla template 404 error page.
Someone can help me ?
What i need to do ?

I use Nginx + Centos.
Thank you all!
