Hi @<1722786133810614272:profile|LazyClams7> , if you see api_server is misconfigured error in the logs for the clearml-fileserver , this basically means the filesserver can't reach the apiserver (it needs to), this doesn't seem to be a client issue. The filessererver tried to reach the apiserver by default using the None endpoint, which should be available inside the docker backend network - you can try to exec into the fileserver container and see if curl to that address works
