Ok I solved it. For anyone who had the same problem. I followed the tutorial using a devcontainer. i forgot to use the docker variable for my host network.

Changing the config to:

     models:
       - provider: self-hosted
         model: openai/gpt-oss-20b
         api_base: "http://host.docker.internal:1234/v1"

did the trick
