This is a bug
EE should not have prevented use of word such as ping and status in URLs.
We will see how quickly we can fix that. For now, you can edit these words in the line:
location ~ ^/(status|ping) {
In files:
/etc/nginx/common/locations.conf
/etc/nginx/common/locations-php7.conf
Please reload nginx after changes using
nginx -t && service nginx reload
