What's wrong, caching plugin not working, NGINX+Wordpress?

Question

Nginx

The Cache Enabler plugin for Wordpress doesn't work with NGINX in my case.
Centos7, Nginx/PHP-FM, WordPress Multisite on subdomains.
Here is the nginx template

server {
    listen      %ip%:%web_ssl_port% ssl http2;
    server_name %domain_idn% %alias_idn%;
    root        %docroot%;
    index       index.php index.html index.htm;
    access_log  /var/log/nginx/domains/%domain%.log combined;
    access_log  /var/log/nginx/domains/%domain%.bytes bytes;
    error_log   /var/log/nginx/domains/%domain%.error.log error;

    ssl         on;
    ssl_certificate      %ssl_pem%;
    ssl_certificate_key  %ssl_key%;

    # CacheEnabler Start
 set $cache_uri $request_uri;

    # bypass cache if POST requests or URLs with a query string
    if ($request_method = POST) {
        set $cache_uri 'nullcache';
    }
    if ($query_string != "") {
        set $cache_uri 'nullcache';
    }

    # bypass cache if URLs containing the following strings
    if ($request_uri ~* "(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {
        set $cache_uri 'nullcache';
    }

    # bypass cache if the cookies containing the following strings
    if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in") {
        set $cache_uri 'nullcache';
    }

    # default html file
    set $cache_enabler_uri '/wp-content/cache/cache-enabler/${http_host}${cache_uri}index.html';

    # webp html file
    if ($http_accept ~* "image/webp") {
        set $cache_enabler_uri '/wp-content/cache/cache-enabler/${http_host}${cache_uri}index-webp.html';
    }
    # CacheEnabler Stop

    include     /etc/nginx/conf.d/webmail.inc*;

    include     %home%/%user%/conf/web/nginx.%domain_idn%.conf*;

  
}

I added this to nginx.conf

open_file_cache          max=10000 inactive=30s;
    open_file_cache_valid    60s;
    open_file_cache_min_uses 2;
    open_file_cache_errors   off;

    fastcgi_cache_path /var/cache/nginx/fcgi levels=1:2 keys_zone=microcache:10m max_size=1024m inactive=1h;

In general, Breeze cache plugin starts up without dancing with a tambourine.
The only thing I do not know is whether it is possible to bypass php in it and access it only if there is no cache. But normally it works right away. Nothing else worked, tried a few.
