i think i found something in my .htaccess
RewriteRule ^in/?$ /wp-login.php?4qzqsadsaqlg3vcxuvnyylm [R,L]
RewriteCond %{HTTP_COOKIE} !^.*wordpress_logged_in_.*$
RewriteRule ^tm/?$ /wp-login.php?4qzqsadsaqlg3vcxuvnyylm &redirect_to=/wp-admin/ [R,L]
RewriteRule ^tm/?$ /wp-admin/?4qzqsadsaqlg3vcxuvnyylm [R,L]
ill try and comment this and see if the problem still persists
PS: i removed the hole .htaccess file, i still get 404
