Why is a WP site giving fastcgi cache: MISS all the time?

Question

Regular Expressions

Somehow I updated the site from two devices at once, and from some time the page was cached, although I set it to be cached from 1 time. But, now, this cannot be repeated ... Caching for authorized users is enabled.
Why is this happening? What could be the reason?

catopen

$text = 'https://www.labnol.org/internet/duplicate-gmail-draft-emails/29124/';

$text = preg_replace(['~^.+/(?=\w+-)~', '~/(\d+)\D*~'], ['', '-$1'], $text);

echo $text; // duplicate-gmail-draft-emails-29124
