Nginx + Wordpress issues

I have setup nginx with wordpress, the frontend works fine but when it comes to login on path /wp-login/ the page isn’t redirecting properly.I have to add /wp-login/index.php to access the backend. This issue maybe from nginx config on location block

location / {
    try_files $uri /index.php$is_args$query_string;
}

is there any setting that i missing?
