I'm trying to set a username/password protection on an Nginx subdirectory, but I'm still able to access the subdirectory without supplying credentials.

The Nginx is running on an AWS CentOS 7 instance.
My default.conf is:

[centos@ip-172-31-35-133 nginx]$ cat /etc/nginx/conf.d/default.conf
server {

location /rbarark_test {
satisfy any;

root /usr/share/nginx/html;
index index.html index.htm;
auth_basic "Restricted area - This system is for the use of authorized users only!";
auth_basic_user_file /etc/nginx/.htpasswd;
}
}
[centos@ip-172-31-35-133 nginx]$

I added a username/password entry to .htpasswd:

[centos@ip-172-31-35-133 nginx]$ ls -ls /etc/nginx/.htpasswd
4 -rw-r--r--. 1 root root 45 Mar 24 23:39 /etc/nginx/.htpasswd
[centos@ip-172-31-35-133 nginx]$

And all the web-site files are at:

[centos@ip-172-31-35-133 nginx]$ ls /usr/share/nginx/html/rbarak_test/en/
amazon-dynamodb-audit-integration-guide.html cockroachdb-integration-guide.html jsonar--solutions-for-agentless-oracle-db-auditing.html os-auditing-solution.html

cloudera-integration-guides.html js oracle-integration-guides.html unified-auditing-solution.html
[centos@ip-172-31-35-133 nginx]$


But still, when I connect my browser to http://18.215.232.30/rbarak_test/?lang=en, I'm not challenged to give a username/password.

Can you see what am I doing wrong?
