htaccess rewrite to nginx config not working - apache

Question

I'm having a problem converting an appache .htaccess file work with nginx.
The .htaccess file
<ifModule mod_rewrite.c>
Allow from 127.0.0.1
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^index(|/)$ index.php
RewriteRule ^logout(|/)$ logout.php
RewriteRule ^keeping/([^/.]+)(|/)$ keeping.php?s=$1
</ifModule>
My Conversion:
location / {
if (!-e $request_filename){
rewrite ^/index(|/)$ /index.php;
}
}
location /logout {
rewrite ^/logout(|/)$ /logout.php;
}
location /kyhsadminpanel {
rewrite ^/keeping/([^/.]+)(|/)$ /keeping.php?s=$1;
}
doesn't work.
It always shows "404 not found" for url's such as /kyhsadminpanel/keeping/index
and /kyhsadminpanel/keeping/news...

You might want to note you used: https://winginx.com/en/htaccess
I tend to use: https://timmehosting.de/htaccess-converter
Here is the result from them.
if (!-d $request_filename){
set $rule_0 1$rule_0;
}
if (!-f $request_filename){
set $rule_0 2$rule_0;
}
if ($rule_0 = "21"){
rewrite ^/index(|/)$ /index.php ;
}
rewrite ^/logout(|/)$ /logout.php ;
rewrite ^/keeping/([^/.]+)(|/)$ /keeping.php?s=$1 ;
