Did you set MinIO credentials? Make sure your aws_access_key_id and aws_secret_access_key is correct.

猜测是s3协议的问题，这个我已经设置了，但是mc config host list出来的是这个配置，在mlflow里链接的是s3://mlflow

mc has its own config, you need to configure the AWS credentials file: https://github.com/sachua/mlflow-docker-compose/blob/8a46cefad2bf3ef785d317894db48b6968083838/README.md?plain=1#LL52C1-L58C8
