The issue you are facing:

I did everything in the guide to activate pretty URL:

  'htaccess.RewriteBase' => '/',
  'overwrite.cli.url' => 'REDACTED',

I ran the command, too. I now have these lines in my .htaccess file:

  RewriteRule . index.php [PT,E=PATH_INFO:$1]
  RewriteBase /

So everything looks good to me. However if I manually remove the index.php part from the URL, I get something like this (e.g.: the news app):
grafik

I don’t know if this is related to my nextcloud server beeing behind a reverse proxy, but I set the config.php parameters for it, so I don’t know. However nextcloud always uses index.php as part of links… So some setting has to be wrong right?

Seems a silly question, but are you using php-fpm? php-fpm cannot use .htaccess but instead uses another .user.ini or something.

I am using a different RewriteRule in Apache. This one works for me.:

RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=Permanent]

Have you also added:

RewriteEngine on

In your vhost file for Nextcloud?

No I am not running php-fpm(should I?), but mod_php.
This is my entire .htaccess file:

  <FilesMatch "\.woff2?$">
    Header set Cache-Control "max-age=604800"
  </FilesMatch>

    SetEnv front_controller_active true

There are 2 IfModule mod_rewrite.c areas. Do they conflict? Do I have to add the RewriteEngine on to both?
