403 Forbidden when importing project

Hi,

I’m trying to import a project exported from a Gitlab instance but when I click the final “Import Project”, I get a 403 for /import/gitlab_project.

The project was exported from a Gitlab instance version 13.8.1 and the instance in which I’m trying to import the project is 13.8.4.

Re-importing the project in the instance from which it was exported works fine.

Both instances are docker-ce instances.

Any ideas?
