To solve this issue, you will have to remove the old cytomine network:
docker network rm cytomine-ce_cytomine-network

Afterward, you will need to rerun the Docker Compose command:
docker compose up -d

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