How to set up ModPagespeed on Apache for a domain with https?

Question

Apache HTTP Server

Installed the ModPagespeed module on the Apache server. The domain works through https. In the pagespeed.conf settings, I specified:

ModPagespeedFetchHttps enable
ModPagespeedMapOriginDomain "http://localhost" "https://site.ru"
ModPagespeedLoadFromFile "https://static.site.ru" "/var/www/web2a/data/www/site.ru/static/"

htaccess:

<IfModule pagespeed_module>
  ModPagespeed on
  ModPagespeedEnableFilters rewrite_css
  ModPagespeedEnableFilters combine_css
  ModPagespeedEnableFilters recompress_images
  ModPagespeedEnableFilters convert_jpeg_to_webp
  ModPagespeedEnableFilters collapse_whitespace
  ModPagespeedEnableFilters remove_comments
</IfModule>

For some reason it doesn't work.
