Package Registry Internal Server Error for Large Files

Hello everyone, I tried to upload a file larger then 1GB to the Package Registry of a Project. Unfortunately it throws only an 'internal server error' message.

The only configuration in the gitlab.rb file is

nginx['client_max_body_size'] = 0

The request to upload a file

curl --header "PRIVATE-TOKEN:<token>" --upload-file large.tar.xz "https://<link>/api/v4/projects/54/packages/generic/test/0.0.1/large.tar.xz?select=package_file"

the response

{message: 500 internal server error}

I checked

/var/log/gitlab/gitlab-rails/production.log

there is only one entry about the upload

Started PUT "/api/v4/projects/54/packages/generic/test/0.0.1/large.tar.xz?select=package_file" for <IP> at 2022-09-26 11:27:10 +0200

Do you have an idea? Could you help me?
