Mimicking UI with API issues

Hellow! Im trying to use the template byecho/simpletuner-image:latest via the API. When i deploy via UI it all works fine and i get a public IP and port that i can ssh/scp into. But when i deploy via Graphql it doesnt work when i try to connect in the shown ip/port in the UI it says connection refused (code interacting with API in screenshot) Another issue im facing is i cant seem to set my containerRegistryAuthId when creating a pod, its not a supported field, as im testing i create and terminate pods frequently and im tetting throttled by docker pull, is there any workaround?
