In my understanding requests still go through

clearml-server

which configuration I left

DefiantHippopotamus88 actually this is Not correct.
clearml-server only acts as a control plane, no actual requests are routed to it, it is used to sync model state, stats etc. not part of the request processing flow itself.
curl: (56) Recv failure: Connection reset by peerThis actually indicates 9090 port is not being listened to...
What's the final docker-compose you are using?
and what are you seeing when running netstat -natp | grep LISTEN ?
