How to reset the cache?

Question

Nginx

Hello everyone, the problem is this, there is a site on opencart 2.3, on Friday evening they uploaded a new design, everything was fine except for the style file for some users, I cleared the cache with the default opencart tools (modifiers, systems, etc.), cleaned cloudflare cache, cleared the nginx cache in my nginx+apache, also rebooted nginx at the beginning, and then the server, replaced expires max with expires 1d in the config, 3 days have already passed, but for some users it still shows the old styles, I forgot to say that most of the users from mobile phones and css go without versions like this

<link href="catalog/view/theme/default/stylesheet/stylesheet.css" rel="stylesheet">

Please help with advice on how to solve this problem.
