We were not able to find or create Copr project packit/cockpit-project-cockpit-machines-1630 specified in the config with the following error:

Cannot create a new Copr project (owner=packit project=cockpit-project-cockpit-machines-1630 chroots=['centos-stream-9-x86_64']): Copr: 'packit/cockpit-project-cockpit-machines-1630' already exists

Please check your configuration for:

1. typos in owner and project name (groups need to be prefixed with @)
2. whether the project name doesn't contain not allowed characters (only letters, digits, underscores, dashes and dots must be used)
3. whether the project itself exists (Packit creates projects only in its own namespace)
4. whether Packit is allowed to build in your Copr project
5. whether your Copr project/group is not private

I have triggered this to get cockpit-project/cockpit#20358.
