Hi urose,
looks like you set your blog url (and perhaps your site url) to https://example.com/blog !
so you need to login to phpMyAdmin or change your siteurl and home options back to entertolearn.com before you can log back in,,,
if you dont have phpmyadmin you can try adding this to your functions.php file:

update_option('siteurl', 'https://www.entertolearn.com');
update_option('home', 'https://www.entertolearn.com/blog/');

that should fix you back up the you should be able to login using https://www.entertolearn.com/wp-admin

best
jeff
