Npm publish to private gitlab instance results in 404

Describe your question in as much detail as possible:
I try to publish a npm package to private gitlab CE instance. I followed the gitlab guide on how to setup npm and my project (npm packages in the Package Registry | GitLab).
I try to publish to the project level endpoint.However, I always get a 404. I cannot see anything special in the gitlab logs but the 404 error.

To publish, I use CI_JOB_TOKEN=<deploy-token> npm publish --verbose

• What are you seeing, and how does that differ from what you expect to see?
  I get a 404, I expect a 200 (or similar success code):

• Consider including screenshots, error messages, and/or other helpful visuals

• What version are you on? Are you using self-managed or GitLab.com?

  • GitLab (Hint: /help): Gitlab CE 14.5.2

• Add the CI configuration from .gitlab-ci.yml and other configuration if relevant (e.g. docker-compose.yml)
  .npmrc

• What troubleshooting steps have you already taken? Can you link to any docs or other resources so we know where you have been?

• I checked if there is an nginx in front of the gitlab nginx ->no
• I rechecked the config multiple times
• I used a personal Access token instead of a deploy token
• I tried the whole procedure via gitlab-ci → without success, same error.

Hi @eddykaya

Did you sort this out in the end? I’ve been having issues with npm publish also…

It seems that this is a misleading error message
there’s still a problem with the authentication…
