Cannot create pipeline for project

Until now I was able to create pipelines for projects hosted in Gitlab self-managed, using my Gitlab Personal Access Token.

Suddenly, I can no longer create new pipelines for projects. I am talking about the project setup page “Pipelines > Add Pipeline”.

When I fill in my Gitlab PAT, I am getting an error message on the bottom right:


GitLab Authentication Error

The token you provided is associated with a different CircleCI account. Please provide a personal access token unique to your user account.


I have another account connected with Github, but there are no projects/pipelines setup in that one.

Does anyone know what can I do?
