Gitlab startup using Docker in endless loop

Problem to solve

I installed Gitlab in a Docker container on an Ubuntu 22.04 workstation following exactly the online instructions. When I start Gitlab in a Docker container using sudo docker run --detach --hostname …
and monitor the progress using:
sudo docker logs -f
the following error messages appears in a never-ending loop:

==> /var/log/gitlab/gitlab-workhorse/current <==
redis: 2024/09/06 18:04:42 pubsub.go:168: redis: discarding bad PubSub connection: EOF
{“error”:“keywatcher: pubsub receive: EOF”,“level”:“error”,“msg”:“”,“time”:“2024-09-06T18:04:42Z”}

What to do?

Thanks
