but i got this error message

It looks like the renderer is attempting to connect to Grafana using localhost, which does not work in a containerized environment because each container has its own network namespace. You need to update your Grafana configuration to point to the correct Grafana server:

[remote_rendering]
url = http://<grafana_container_name>:3000

Replace <grafana_container_name> with the name of the Grafana container in your Docker Compose configuration.
