Cause

Nginx is not installed or is not enabled on the server:

In Tools & Settings > Services Management Reverse Proxy Server (nginx) is marked as:

  • Service is not installed
    or 
  • Service is not running

the same can be checked using:

# plesk bin extension -e kolab troubleshoot.php > report.txt | cat
array (
'code' => 1,
'stdout' => '',
'stderr' => 'Error: Nginx component is not installed.
',
)

Resolution

  1. Log into Plesk.
  2. Install or enable Nginx:
    In case Reverse Proxy Server (nginx) is marked as Service is not installed
    install it in Tools & Settings > Updates >Add/remove components page (Web hosting >Nginx web server and reverse proxy server menu)
    In case Reverse Proxy Server (nginx) is marked as Service is not running
    enable it by clicking Start the Service:

    Hello @U. Schütze,

    Could you please send the screen shots showing it works but not integrated? If it is installed via the Extensions menu in Plesk, it should be integrated already.

    Also, make sure your server satisfies the Seafile requirements:
