To solve this issue, you will have to remove the old cytomine network:

docker network rm cytomine-ce_cytomine-network
1

Afterward, you will need to rerun the Docker Compose command:

docker compose up -d
1

This issue occurs because the current version uses static IP assignment for containers, whereas the previous version assigned IPs dynamically.
