I had a similar issue and was able to resolve it by checking the network configuration in Docker-Compose. Make sure Neo4j is running in the correct network and accessible from other containers.

A useful approach is to set NEO4J_URI as bolt://neo4j:7687 if “neo4j” is the service name in your docker-compose.yml. Also, checking the container logs (docker logs ) can provide more insights into potential errors.

I documented a similar case here: https://ollama.com/IBLAG/Certification
