In a self hosted server I am getting a similar issue to this:
None

The agent-services keeps restarting repetitively.
In the docker logs I am getting this error:

clearml_agent: ERROR: It seems *api_server* is misconfigured. Is this the ClearML API server None

I don't understand where the None comes from and what should be dones instead.
This is the agent-services section of my docker-compose file

  agent-services:
    networks:
      - clearml_backend
    container_name: clearml-agent-services
