I got the same problem but I could fix it in the  clearml.conf  file. Please check the role, key, secretkey in  clearml.conf  file
@<1571308010351890432:profile|HurtAnt92> , if this is on the fileserver log, this most likely means that the fileserver can't reach the apiserver component - how did you install the server, exactly? Did you use the docker compose deployment ?
Looks like you're having issues connecting to the server through the SDK. Are you able to access the webUI? Is it a self hosted server?
