Issue Rewrite shows a File not Found error

[Androxin]

Hello,

I have a freshly set up server with Debian 9 and Plesk (version 18.0.27 Update #1) by IONOS.
In Plesk I have set up a domain/webspace. There are no other settings I have made. Nginx serves as reverse proxy.
Basically everything works as well. Only Rewrite makes me feel tired.
It behaves totally strange. Redirections to other domains work. But the reference to a script does not.

I want URLs to be rewritten as follows: domain.de/etwas > domain.de/index.php/etwas

I am already using the configuration described below successfully on another web server.

.htaccess:

RewriteEngine On

RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [QSA,L]

When I open the domain "domain.de/etwas", the browser displays the error message "File not found." along with the HTTP status 404. This is a bit strange, because the regular 404 page is not shown.

In the error_log it is written:
[Sat Jun 06 22:39:44.985055 2020] [proxy_fcgi:error] [pid 64022:tid 139995009009408] [client 11.22.33.44:50444] AH01071: Got error 'Primary script unknown'.


As this is not really informative, I have configured "LogLevel alert rewrite:trace8" as an additional directive.

Here is an extract of the error_log:

I think that the rewrite actually works. In the last line of the log file the path is correctly composed. If you enter it manually in your browser ("domain.de/index.php/etwas"), it will also work.

As a test, I have deactivated the reverse proxy service. But this did not affect the error.


Does anybody have an idea in which direction I could do further research or has anybody already had this problem and a solution for it?
