Invalid hash for .htaccess after upgrade to 15.0.4

OS: Ubuntu 18.04.1
Nextcloud version: 15.0.4

After I upgraded from 15.0 to 15.0.4, I had to update my .htaccess file from /var/www/html, the Newtcloud web path, to include some best practicies from Nextcloud (settings/admin/overview).
The thing is that after that I received this error in the Overview page:
" Some files have not passed the integrity check."

I tried:

  • occ maintenance:update:htaccess
  • /var/www/html/cron.php
  • occ files:scan --all
  • Nextcloud forum
  • ‘integrity.check.disabled’ => true, in config.php (I don’t want to disable this security feature)
  • Google

Nothing works, except if I put the original and untouched .htaccess file from the Nextcloud archive.
I saw the “Code signing”** page, but I don’t understand how can I do it on this file .htaccess.
Any thoughts/ideas/comments?
