Redirection problem with similar URL’s

I have strange problem with redirection in WordPress. There are two pages with similar permalink:

https://www.example.com/finance

https://www.example.com/finance-and-accounting

After entering on /finance-and-accounting address, WordPress redirects to the /finance page.

When I change /finance-and-accounting to, for example /123finance-and-accounting it’s work fine, but I need current address. I tought that change current address to something working and add redirect from /finance-and-accounting to new address will good solution but…

Wordpress root folder don’t have .htacces file, but includes nginx.conf file, so I guess it’s on nginx server. Important – this nginx.conf file was empty.

I tried add following code to nginx.conf:

location /finance-and-accounting {
  rewrite ^(.*)$ https://www.example.com/new-address redirect;
}

and

location https://www.example.com/finance-and-accounting {
  rewrite ^(.*)$ https://www.example.com/new-address redirect;
}

also
remove_action('template_redirect', 'redirect_canonical');
in functions.php

But it’s not work. It still redirect to /finance page.
