Advanced HTTP Basic Auth query with determine IP address

Hello forum user, I have a page that can only be reached via IP address. Now I want to make this page open from the outside. But then an Auth _ Basic query is to come up.


I entered the following line in the domain configuration.

location / {
if ($remote_addr != XXX.XXX.XXX.XX)
{
try_files $uri $uri/ =404;
auth_basic "Externe Zugriffskontrolle";
auth_basic_user_file /.../...../........../........../.htpasswd;
}
}


Unfortunately, I keep getting the error message: "nginx: [emerg] " try _ files "directive is not allowed here in ... " Without a query it works. But then the query is always there. Can anyone help me?

Thanks in advance ...
