This is coming from the HIFIS team:

Dear Helmholtz Cloud users: Helmholtz Codebase [1] and Mattermost [2] will undergo planned maintenance and will not be accessible from 2025-05-22 16:00 CEST, for approx. 1 hour. In preparation for the GitLab major upgrade 18, a planned maintenance of the database is taking place. Access to both services is not possible during this time. With regards, the HIFIS team

In practice: Blablador’s API server won’t be able to authenticate the token, so it will fail. I’m sorry for the disturbance. Best, Alex
