I am not able to login to wordpress admin

I recently changed my primary domain and now I am not able to login to wordpress admin as it continues to redirect to http://preservationsolutions.guru/wp-login.php?redirect_to=http%3A%2F%2Fgingerweatherford.com%2Fwp-admin%2F&reauth=1

when I change the address to gingerweatherford.com/wp-login and try to login with admin username and password it redirects to http://preservationsolutions.guru/wp-login.php and gives Error 404 not found
