Some Docker images fail to start

Images for worker, backend and frontend keep restarting when following the steps in de readme file. After cloning the repository, I executed make fetch-modules and docker compose up. Incidentally, docker compose up outputs:

``` ! worker Warning pull access denied for buildingsmart/validationsvc-backend, repository does not exist or may require 'docker login'
! backend Warning pull access denied for buildingsmart/validationsvc-backend, repository does not exist or may require 'docker login'
```

I verified that the repo buildingsmart/validationsvc-backend indeed does not exist.

Terminal output:
```
